Fiona borrows $5,000 to help pay for a car. The interest rate on the loan is 7.5%. She plans to pay back the loan in 3 years. How much will she have to pay back in TOTAL at the end of the 3 years? Show your work!

Total amount = $6125

Step-by-step explanation:

Given the following data;

Principal = $5000

Interest rate = 7.5%

Time = 3 years

To find the simple interest;

Mathematically, simple interest is calculated using this formula;

Where;

S.I is simple interest.

P is the principal.

R is the interest rate.

T is the time.

Substituting into the equation, we have;

S.I = $1125

Next, we find the total amount to be paid back;

Total amount = principal + simple interest

Total amount = 5000 + 1125

Total amount = $6125

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
