One of your friends gives you $10 for a charity walkathon. Another friend gives you an amount per mile. After 5 miles, you have raised $13.50 total. Write an equation in slope-intercept form that represents the amount y of money you have raised after x miles.
y=
Answer:
y = 0.70x- 10.00
Step-by-step explanation:
-- Since one friend gave you 10.00 ,subtractthis from the 13.50 to give you the amount earned by walking the 5 miles
-- 13.5-10.00 = $3.50
-- Since you walked 5 miles, divide by 5 to give you 0.70 per mile earned.
So, an equation that represents the amount of money earned is:
y = 0.70x- 10.00 . This is in slope-intercept form; the slope is $0.70 and represents the amount of money earned per mile and the intercept is $10.00 and represents the initial amount of money that you were given.

Maribel deposited $1,500 in a new account at her bank. -The bank pays 4.5% annual simple interest on this account. -Maribel did not make any additional deposits or withdrawals. What is the balance of the account at the end of five years?
Answer:
1500+337.50 = $1,837.5
Step-by-step explanation:
You want to calculate the interest on $1500 at 4.5% interest per year after 5 year(s).
The formula we'll use for this is the simple interest formula, or:
I = P x r x t
Where:
P is the principal amount, $1500.00.
r is the interest rate, 4.5% per year, or in decimal form, 4.5/100=0.045.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 1500 × 0.045 × 5 to get that:
The interest is: $337.50

Solve the equation 186+10x=25.5x to find how many diving lessons x Jacy can take for the cost to be the same with and without a membership.
__ lesson(s)
Answer:12 lessons
Steps in image below:
The number of lessons that take for the cost to be the same with and without a membership will be 12.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
The equation is given below.
186 + 10x = 25.5x
Simplify the equation, then we have
25.5x - 10x = 186
15.5x = 186
x = 186 / 15.5
x = 12
The number of lessons that take for the cost to be the same with and without a membership will be 12.

Valerie bought a guitar at a sale price of S = 0.8g, where g represents the original cost of the guitar. Which expression shows the sale price in a way that emphasizes the percent discount that she received? A S = (1 + 0.8). B S= (1 +0.2) g C S= (1 - 0.8). D S = (1 – 0.2) g
Answer:
D S = (1 - 0.2)g
Step-by-step explanation:
The original price of the guitar was g.
She paid 0.8g.
0.8g = 0.80g = 80% of g
If she paid 80% of the price, that means the discount was 20%.
100% - 20% = 1 - 0.2
Subtracting 20% form the whole 100% of the price is the same as subtracting 0.2 from the whole price of 1.
Answer: D S = (1 - 0.2)g
As a fundraiser, the Robotics team is selling cookies. The cost to make each cookie can be written as c(x)=0.25x+0.5 and the functions that represents the amount they sell the cookie for can be written as s(x)=2x. Write a function represents the profit, P(x)
Answer:
The profit is 1.75x-0.5
Step-by-step explanation:
Mathematically,
profit = sales - cost
So with respect to this case, we have that;
Profit = s(x) - c(x)
Profit = 2x - (0.25x + 0.5)
Profit = 2x - 0.25x -0.5
Profit = 1.75x - 0.5

(HELP! I HAVE NO TIME) At 2pm, a store had sold 15 packs of toilet paper. By 5pm, the store had sold 57 packs of toilet paper. What is the average rate of change?
[tex]\mathrm {Hey, there!}[/tex]
Let's solve your problem:
The answer would be 280%.
We know the following information:
2pm - 15 toilet paper rolls
5pm - 57 toilet paper rolls
We have to find the percent rate of change.
Here is how we will do this problem:
First, Set up a ratio:
Change in the quantity [15 - 57]
-------------------------------------
Original quantity [15]
57 - 15 = 42
Next, we will divide. the ratio.
Given quantity - 42
Number of packs sold at 2pm - 15
Fraction - 42/15
Convert the fraction to a decimal.
Fraction - 42/15
Decimal - 2.8
Make the decimal to a percent.
Decimal - 2.8
Percent - 28%
Add a zero to the 28.
Our answer is 280%
Answer:
14 packs per hourStep-by-step explanation:
2pm ⇒ sold 15 packs 5pm ⇒ sold 57 packsAverage rate of change = change in sale/ change in time
(57 - 15) / (5 - 2) = 42/3 = 14 packs per hourFind the missing side lengths of each triangle.

A section of a railway has a slope of approximately 0.47. In this section, a vertical change of 1 unit corresponds to a horizontal change of what length? Round your answer to the nearest hundredth.
Step-by-step explanation:
A slope of 0.47 means that, for every 100 feet of horizontal change, the vertical rise = 47 feet
We can use a proportion here
0.47 / 1 = 1 / x
Cross-multiply
0.47x = 1*1
0.47x = 1
Divide both sides by 0.47
x = about 2.13 units
