Using the formula of P(1 + r)^n = x where p represents the initial value, r represents the rate and n represents the number of years and x is our final output. We want to find P so we have to make it the subject of the equation.
1 + 0.04 = 1.04 1.04^18 = 2.025816515 Then divide the total amount by this to get 185,110.5454 Therefore the answer is $185,110.55
