2. if a home mortgage has a term of 15 years and a payment of $1,000, what is the loan amount? (assume that there are no interest-free mortgages)

When you say "no interest-free mortgages", this would mean that there is an interest. However, the problem does not state any interest rate. So, let's just assume a value for the interest rate. In US, the current 15-year mortgage rate is 2.88%. (source:https://ycharts.com/indicators/15_year_mortgage_rate)

Then,

F = P (1 + i)^n

where F is the future worth, P is the present worth, i is the interest and n is the number of years.

F = $1000 (1+0.0288)^15
F = $1,530.96

On the event that there is no interest (which is unlikely), the amount would still be $1000.

Ibelieve the answer is medicaid.
