Brett earns a base salary of £78 per week plus a commission of 20% of sales. How much did Brett make last week if he managed to sell £85 worth of merchandise?
By taking the 20 percent of £85 and adding that to the base salary, we can see that last week Brett earned £95
How much did Brett make last week?Here we need to work with percentages. We know that Brett wins a commission of 20% of sales.
So, if he sells a total amount of A (A is in dollars). Then what he gets is:
0.2*A
Where 0.2 is the decimal form of 20%.
Here we know that Brett wins £78 as a base, and last week he sell a total of £85, then the amount he gets by the commission is:
0.2* £85 = £17
Adding that to the base he already earns each week, we get:
£78 + £17 = £95
In this way, we conclude that last week Brett earned £95

Which equation shows a line perpendicular to y = 3x + 2
a) y-1=1/3 (x-2)
b) y-1=3(x-2)
c) y-1=-1/3(x-2)
d) y-1=-3(x-2)
The straight line y-1=-1/3(x-2) is perpendicular to y = 3x + 2 .
The common form for two-variable linear equations is Ax + By = C which is also the general form of a straight line.
For instance, the linear equation 6x+5y=11 uses standard form. Finding an equation's two intercepts (x and y) is fairly straightforward with this procedure.
The cartesian equation for a straight line is Y = mx + c, where m stands for the gradient or slope of the line and c for the point at which it intersects the y-axis.
If two geometrical objects cross at a right angle, they are perpendicular.
We know that when two line are perpendicular the product of their respective slopes equal to -1.
Now in the given options let us find the slope of each line.
a) y-1=1/3 (x-2)
slope = 1/3
b) y-1=3(x-2)
slope = 3
c) y-1=-1/3(x-2)
slope = -1/3
d) y-1=-3(x-2)
slope = -3
Therefore the slope of the third equation is the negative reciprocal of the slope of the given line.
Hence y-1=-1/3(x-2) is perpendicular to y = 3x + 2 .

write an equation for there consevite integers whose sum id 306
The equation for three consecutive integers whose sum is 36 is n + (n+1) + (n+2) = 306.
What is an equation?A mathematical statement called an equation includes the sign "equal to" between two expressions with equal values.
What are consecutive numbers?Whole numbers that follow one another without a gap are known as consecutive integers.
Given the sum of three consecutive integers = 306
Let the integers be n, n+1, n+2
Then, n + (n+1) + (n+2) = 306
⇒3n + 3 = 306
⇒n = 303/3
⇒n = 101
Hence, n+1 = 102 and n+2 = 103
Therefore, the equation for three consecutive integers whose sum is 36 is n + (n+1) + (n+2) = 306.

How can you write the expression using rational exponents?
5 square root n4
By using exponent properties, we can see that the equivalent expressions are:
[tex]5*\sqrt{n^4} = 5*n^2[/tex]
How to rewrite the expression?Here we need to use some rules for exponents and roots. Remember that:
[tex]\sqrt[n]{x} = x^{1/n}[/tex]
We also will use that:
[tex](a^n)^m = a^{n*m}[/tex]
Now we have the following expression:

Particularly, the square root is equivalent to an exponent of 1/2, then we can write:
[tex]5*\sqrt{n^4} = 5*(n^4)^{1/2}[/tex]
Using the second property we can rewrite:
[tex]5*(n^4)^{1/2} = 5*n^{4*1/2} = 5*n^2[/tex]

The speed of a car from point A to D is m/s however the velocity is 10 m/s due West. Calculate the speed of vehicle in m/s if it covers a distance of 1.5 km in 5 minutes.
Speed of car is 5 m/sec
What is speed?
In ordinary language and kinematics, an object's speed is defined as the magnitude of its position change over time or the magnitude of its position change per unit of time; it is therefore a scalar number. The distance traveled by an item in a time interval is divided by the duration of the period; the instantaneous speed is the limitation of the average speed as the length of time period tends to zero. Velocity is not the same as speed. Distance divided by time is the dimension of speed. The metre per second (m/s) is the SI unit of speed, while the kilometre per hour (km/h) is the usual unit.
The speed of the car = 1.5/5 km/min = 0.3 km/min
Speed in m/sec = 0.3x1000/60 = 5m/sec
Hence, speed of car = 5 m/sec

Neil bought a house for £235 000
In the first year the value of the house depreciated by 4%
In each of years 2 and 3 the value of the house increased by 6%
Work out the value of the house at the end of year 3
Answer:
Based on the given conditions, formulate: 235000×(1+1-4%)
Calculate the sum or difference:235000×(2-0.04)
Calculate the sum or difference:235000×1.96
Calculate the product or quotient:460600
get the result:460600
So the answer is 460600
Answer:
£ 253,484.16
Step-by-step explanation:
Cost of house for first year = £235,000
Year 1
Depreciation for first year is 4% = 4/100
Depreciation in £ = 235,000 x 4/100 = £9,400
Effective value of house at end of first year
= 235000 - 9400 = £225,600
Year 2
In the second year the house value increased by 6% = 6/100
So total increase in £ at the end of year 2 with an initial value of £225,600 = £225,600 x 6/100 = £13,536
So actual value of house at end of year 2
= £225,600 + £13,536
= £239,136
Year 3
The value increased by 6% for year 3.
Value at beginning of year 3 = £239,136
Increase in value at 6% = £239,136 x 6/100 = £14,348.16
Total Value at end of year 3
= £239,136 + £14,348.16
= £253,484.16
Answer: £253,484.16
Note
Another way of quickly calculating this is noting that 4% depreciation means the new value is (1 - 4%) of initial value = 1 - 4/100 = 0.96
An increase of 6% means the new value will be 1.06 times the initial value
So the value of the house after 4% depreciation for the first year and 6% appreciation for the next 2 years
= 235000 x (0.96)(1.06)(1.06) = 253,484.16

GCF(a, b)• LCM (a, b) = 77
What are the possible values of a and b?
The variables a and b have a possible value of 7 and 11
How to determine the possible values of a and b?The given parameters are
GCF(a, b)• LCM (a, b) = 77
As a general rule, the product of two numbers equals the product of the greatest common factor and the least common multiple of the numbers
This implies that
a * b = GCF(a, b)• LCM (a, b)
So, we have
a * b = 77
Express 77 as 7 * 11
a * b = 7 * 11
By comparison, we have
a = 7 and b = 11
Hence, the possible values are a = 7 and b = 11

2) Mr. Jonas took out a loan of $12,400. The interest rate is 3% per year, and the
interest is not compounded. How much amount will Mr. Jonas have to repay
after 4 years?
The amount which Mr. Jonas will have to repay after 4 years is $13,888 when the interest rate is 3% per year on a loan of $12,400.
According to the question,
We have the following details:
The amount of the loan or the principal amount = $12,400
Interest rate = 3% per year
Time = 4 years
Now, it is given that the interest is not a compound interest. So, the total interest can be found using the formula of simple interest.
Simple Interest (S.I.) = (Principal*rate*time)/100
S.I. = (12400*3*4)/100
S.I. = (12400*12)/100
S.I. = 148800/100
S.I. = $1,488
Now, the total amount Mr. Jonas have to repay will be the sum of the loan he has taken out and the simple interest after 4 years.
Total amount = Principal + S.I.
Total amount = 12400+1488
Total amount = $13,888
Hence, the total amount of loan Mr. Jonas has to repay is $13,888.

Round to the nearest tenth if

If she priced scooter for $15.50 and ended up selling it for $10.75, then the percentage of decrease in the price of the scooter is 30.64%
The initial price of the scooter = $15.50
The selling price of the scooter = $10.75
The amount decrease in the price of the scooter = Initial price of the scooter - The selling price of the scooter
= 15.50-10.75

The percent of decrease in the price of the scooter = (The amount decrease in the price of the scooter ÷ The initial price of the scooter)×100
