Question

Meghan borrowed $900 from her grandmother to buy a used car. Her grandmother doesn'tcharge any interest andMeghan has been making $95 payments each month. What is theequation that models the amount Meghan owes? Graph this equation.

Answer 1

D=9000-95x

1) Gathering the data from the question

Meghan borrowed: $9000

Monthly Payments: $ 95

2) Let's model this equation:

Since there's no interest rate, and calling D the debt, Meghan's debt can be calculated by:

D=9000-95x

x, is the number of months.

D is the Total Debt.

3) On the First Month:

D= 9000-95(1)

D=9000-95

D=8905

And so on...

3) The Graph of this function:

This is a linear function.
