Identify Formula: Identify the formula for compound interest which is A=P(1+r/n)(nt), where P is the principal amount, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the time in years.
Plug Values: Plug in the values: P=15000, r=0.0325, n=12, and t=20 into the formula.
Calculate Rate per Period: Calculate the rate per period by dividing the annual rate by the number of periods per year: (0.0325)/(12).
Calculate Base of Exponent: Calculate (1+(0.0325)/(12)) to find the base of the exponent.
Raise to Power: Raise the base to the power of the total number of compounding periods: 12×20.
Multiply Principal: Multiply the principal amount by the result from the previous step to find the final value.
Perform Calculations: Perform the calculations: 15000(1+120.0325)12×20.
