Answer:
$78,443.29
Explanation:
we need to use the present value of an annuity formula:
the formula used to determine the present value factor of an annuity is:
present value annuity factor = [1 - 1/(1 + i)ⁿ ] / i
we must divide this into 2 parts:
the first part will deal with the $2,000 monthly payment
the second part deals with the $1,000 monthly payment
i = 9.75% / 12 = 0.8125%
n (first part) = 36
n (second part) = 24
the PV annuity factor for first part = [1 - 1/(1 + 0.8125%)³⁶ ] / 0.8125% = 31.1043
the PV annuity factor for first part = [1 - 1/(1 + 0.8125%)²⁴ ] / 0.8125% = 21.7251
loan = ($2,000 x 31.1043) + ($1,000 x 21.7251)//(1 + 0.8125%)³⁶ = $62,208.60 + $16,234.69 = $78,443.29
= [1 - 1/(1 + 0.0069942)240 ] / 0.0069942 = 116.135183
