I need help getting the answer for this problem.

Question

Suppose there is $1,500 in a savings account at the end of a certain period of time. The original amount invested was $1,200 at a 7.95% simple annual interest rate. How long, in years, was the money invested? Round your answer to one decimal place.

Answer 1

starting principal P = $1200

$300 interest was earned...

7.95% = 0.0795

I = Prt

300 = 1200*0.795* t

300 = 95.4 * t

t = 3.1
