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.

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

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
