Given:
Amount = $25000
Time = 30 - year
APR = 4.5
Find: Monthly payment
Sol:.
Finace charge = total installment payment + down payment
Down payment = 0
[tex]\begin{gathered} APR \\ A=\left(P\left(1+rt\right)\right) \end{gathered}[/tex][tex]\begin{gathered} A=\left(25000\left(1+\frac{4.5}{100}\times30\right?\right? \\ A=25000\left(1+1.35\right) \\ A=25000\times2.35 \\ A=58750 \end{gathered}[/tex]For 30 years the total amount is 58750
So monthly payment is:
[tex]\begin{gathered} Per\text{ year payment}=\frac{58750}{30} \\ =1958.33 \end{gathered}[/tex]The monthly payment is:
[tex]\begin{gathered} =\frac{1958.33}{12} \\ =163.194 \end{gathered}[/tex]Brad's monthly payment is $163.194
