R = 3%/year
Equation:r = (1/t)(A/P - 1)
Calculation:Solving our equation:r = (1/7)((5445/4500) - 1) = 0.03r = 0.03
Converting r decimal to R a percentageR = 0.03 * 100 = 3%/year
The interest rate required to get a total amount, principal plus interest, of $5,445.00 from simple interest on a principal of $4,500.00 over 7 years is 3% per year.
