Amount = P*(1 + r/n) n*t
Where:
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per year
t = the number of years the money is invested or borrowed for
A = 25000*(1 + 0.0675/4)4*18
A = 25000*(1 + 0.016875)72
Can you take it from here?
