[pic] 12.1 1. The headic mortgage would be such that the present survey of the mortgage come in is equal to the contribute amount. To find the periodic mortgage amount, we use the PV of annuity formula since monthly stipend is the annuity and the PV is the add amount. The PV of annuity is stipulation as PV = PMT [(1 - (1 / (1 + i)^n)) / i] Where PV = loan amount PMT = monthly mortgage payment i = monthly interest rate n = monthly periods Using the in a higher place formula we calculate the monthly payments for the given rates and loan amount and time period a. 6.25%, 15 year, $150,000 150,000 = PMT [(1-(1/(1+6.25%/12)^(15X12))/6.25%/12] PMT = $1,286.13 come amount paid = 1,286.13 X 15 years X 12 months = 231,503.40 Loan amount = $150,000 Interest paid = 231,503.40-150,000 = $81,503.4 b. 6.25%, 15 years, 175,000 175,000 = PMT [(1-(1/(1+6.25%/12)^(15X12))/6.25%/12] PMT = $1,500.49 combine amount paid = 1,500.49 X 15 x 12 =270,088.20 Loan amount = 17 5,000 Interest paid = 270,088.20 175,000 = 95,088.20 Doing the comparable flair we are able to fill the table Monthly remuneration is | |6.25% |6.50% |7% | |Amount |15 |20 |30 | | 150,000 |$1,286.13 |$1,118.36 |$997.95 | | 175,000 |$1,500.49 |$1,304.75 |$1,164.28 | | 200,000 |$1,714.85 |$1,491.15 |$1,330.
