A) \$1,250                    B) \$765.87                  C) \$994.38                  D) \$8,420.13

Alexis is ready to buy her house. She will purchase the \$450,000 house with her \$75,000 down payment and finance the rest with a 20 year, 6% annual rate mortgage with equal end of month payments. What will be her monthly payment?

A) \$2,134.76               B) \$3,223.94               C) \$1,701.69               D) \$2,686.62

Question 1

Future value of Annuity = A [((1+r)n-1) / r]

Where

A - Annuity payment = ?

r - rate per period = .09/12 = 0.0075

n - no. of periods = 5*12 = 60

75000 = A* [((1+.0075)^60 -1) / .0075]

= A* [(1.56568102694 -1) / .0075]

= A*(0.56568102694/.0075)

= A*75.4241369253

A = 75000/75.4241369253

= \$994.38

Question 2

EMI = [P * I * (1+I)^N]/[(1+I)^N-1]

P =loan amount or Principal = 450000-75000 = 375000

I = Interest rate per month = .06/12 = 0.005
N = the number of installments = 20*12 = 240

EMI = [375000*.005*1.005^240]/[1.005^240-1]

= [375000*.005*3.31020447581]/[3.31020447581-1]

= 6206.63339214/2.31020447581

= \$2,686.62
