Audrey earned $1125 from an investment of $6000 over 5 years. What was the annual simple interest rate applied to this investment?

Answer 1

If I have yearly interest = x on principal = P

after 5 years the total is T= P*(1+x)⁵

leads to

1.035=(7125/6000)^(1/5)

Answer 2

i = p * r * t

1125 = (5000)(r)(5)

Can you solve for r and answer?
