Use the function in which r is the annual interest rate, P is the principal, and A is the amount of money after t years. What is the interest rate of the account? A = P(1 + r)t

A.) 1.04%
*B.) 3.6%
C.) 5.4%

• Math -

16099.44 = 15000(1+i)^2
1.073296 = (1+i)^2
1+i = √1.073... = 1.036
i = .036 or 3.6%
