Rachel invested $7511 in an account at a rate of 2% and gained $ 600 88 in interest. how
many years did she invest her money if the interest was caluculated using the simple interest
formula?

4 Years

Step-by-step explanation:

With the simple Interest formula  you take the starting money, multiply it by the interest rate and then multiply that by how many times interest is given.  Since the question mentions years I'm assuming the interest is given annually.

Here we are missing a piece of that but have the final answer.  Anyway, if we say the starting money is P, the interest rate is R and the number of times interest is taken is T and the final amount is A we can plug in

PRT = A

7511 * .02 * T = 600.88

T = 600.88/(7511 * .02)

T = 4

So that's 4 years

answer is b
