Answer 1

Question:

Harry took a loan from the bank. D represents Harry's remaining debt (in USD) after t months.

`D=-200t+9000`

What was the size of Harry's loan?

Answer:

Remember that when modeling a problem like this with the general formula for linear equations:

`y=mx+b`

m represents a quantity that varies, and b is a fixed quantity.

For this problem, that would mean that Harry took a loan of $9,000 , and that he's paying $200 to the bank each month to cover his loan.

Therefore, Harry's loan was $9,000
