Answer:

a. $1,147.20

Explanation:

Simple interest means the same amount will be paid as interest per year.

We will use the following formula to solve for Olivia's interest after 7 years.

Interest = principal* interest rate* time

Principal= $800

Interest rate= 6.2%

Time= 7 years

Interest= 800* 0.062* 7

Interest= $347.20

So the total money owed to Olivia is = 800+ 347.20= $1,147.20
