Answer:

  increase

Step-by-step explanation:

Your cost function appears to be an exponential function of the form ...

  c(x) = (initial cost)·(growth factor)^x

When the growth factor (1.03) is greater than 1, it means the exponential function is increasing with x (time).

The cost function increases with time.

Elza [17]

Answer:

$637.50

Step-by-step explanation:

According to the Question,

  • Given That, A seller of the property listed at $200,000 excepted a 90% offer the home appraised at $185,000 and the buyers obtained a loan for 85% for 30 years at 5% interest

Thus, the first months interest is

$200,000 list price x 0.90 = $180,000 contract sales price.

Since lender always uses the less of the appraised value or the contract sales price, use $180,00 for the remainder of the calculations.

  • $180,000 contract sales price x 0.85 LTV = $153,000 loan.
  • $153,000 loan x 0.05 interest rate = $7,650 annual interest.
  • $7,650 ÷ 12 = $637.50 monthly interest payment for the first month.
