Question

Jonathan bought a new computer for $1,728 using the electronics store's finance plan. He will pay $96 a month for 18 months. Which equation can Jonathan use to find out how much money he still owes after each month of the plan?

Answer 1

1728 = 96x   x=Months of payments

Answer 2

`y=1728-96x`

Explanation:

Given : Cost of computer = $1728

He will pay $96 a month for 18 months.

To Find: Which equation can Jonathan use to find out how much money he still owes after each month of the plan?

Solution:

He pays per month = $96

Let the number of months be x

So, He pays in x months = 96x

Since the total Cost of computer is $1728

So, amount left to be paid =
`1728-96x`

Let y be the unpaid amount after x months

So, equation becomes :
`y=1728-96x`

Hence An equation can Jonathan use to find out how much money he still owes after each month of the plan is
`y=1728-96x`
