Step 1 :We are given a loan of $120,000 and asked to calculate the monthly payment for two options: a 30-year loan at an APR of 10% and a 15-year loan at an APR of 9.5%.
Step 2 :We use the formula for the monthly payment on a mortgage: \[M = P\left[\frac{r(1+r)^n}{(1+r)^n – 1}\right]\] where: M is the monthly payment, P is the principal loan amount, r is the monthly interest rate (annual interest rate divided by 12), and n is the number of payments (the number of months you will be paying the loan).
Step 3 :For the first option, we substitute the given values into the formula: \[M = 120000\left[\frac{0.00833(1+0.00833)^{360}}{(1+0.00833)^{360} – 1}\right]\] This simplifies to approximately $1054.01.
Step 4 :For the second option, we substitute the given values into the formula: \[M = 120000\left[\frac{0.00792(1+0.00792)^{180}}{(1+0.00792)^{180} – 1}\right]\] This simplifies to approximately $1237.09.
Step 5 :\(\boxed{\text{Final Answer:}}\) The monthly payment for the first option is approximately $1054.01. The monthly payment for the second option is approximately $1237.09.
