Explanation / Answer

1.

(a)

Loan amount = $16,000 - $1,000 = $15,000

Monthly interest rate = 5.95%/12 = 0.496%

Number of payments to be made = 4 x 12 = 48

The amount of monthly payment can be determined by dividing the loan amount by the present value interest factor of an ordinary annuity of $1 per period at 0.496% for 48 periods.

Therefore,

Payment each month = Loan amount/PVIFA(0.496%,48) = $15,000/42.6202 = $351.95

(b)

Interest paid the first month = Loan amount x monthly interest rate = $15,000 x 0.496% = $74.40

Principal paid the first month = Monthly payment - interest = $351.95 - $74.40 = $277.55

(c)

Balance of loan at the end of first month = Loan amount - Principal paid the first month = $15,000 - $277.55 = $14,722.45
