If x is negative and y is positive it's QII
If x and y are negative, it's QIII
If x is positive and y is negative It's QIV

So the answer is C

Suppose the Bainters purchase the $150,000.00 home with a 20% down payment, a 30-year mortgage, and an interest rate of 4.2%. An
Elden [556K]

Answer:

  $809.32

Step-by-step explanation:

The loan amount is 80% of $150,000, or $120,000. The monthly payment of principal and interest is $586.82.

The total annual expense for taxes and insurance is $1920 +750 = $2670, so the monthly expense is $2670/12 = $222.50.

Then the total of payments for mortgage and escrow will be ...

  $586.82 +222.50 = $809.32

__

The monthly P&I payment is given by ...

  A = P(i/12)/(1 -(1 +i/12)^(-12t)) . . . . . where i is the annual interest rate, t is the number of years, and P is the amount financed.

  A = $120,000(0.042/12)/(1 -(1 +0.042/12)^(-12·30)) ≈ $586.82

__

A spreadsheet or financial calculator can be useful for calculating payments, though the formula isn't difficult to use.
