Answer
Explanation
The data given are:
The present value, Pv = $1840
Rate, r = 14.5% = 14.5/100 = 0.145
The time is 18 months, and in years, t = 18/12 = 1.5 years
Since the Present value is known, then the future value can be calculated by the formula:
[tex]\begin{gathered} Fv=Pv(1+r)^n \\ Fv=1840(1+0.145)^{1.5} \\ Fv=1840\times1.225 \\ Fv=2254 \end{gathered}[/tex]So to know the monthly installment payment, we divide Future value by 18, that is,
[tex]\frac{2254}{18}=125.22[/tex]Therefore the monthly payment is $125.22
