Try this question

Bernie Madoff wants you to get a really nice car that is worth $25000 with no down payment and even lower monthly payment than the Bank of Nobody.

He also gives you $500 cash for buying the car. (D = –500)

Bernie Madoff uses this algebraic formula to determine your monthly payment.

1.13T  × 1.18³ = 480M + D

where T is the price of the car

1.13 is the 13% HST (thus 1.13T is the total cost you must pay)

M is your monthly payment

D is the down payment

1.18 is the interest charges for your low money payment

What is the 480?

How much will the car be after all the interest charges?

How many years will it take you to pay off the car?

Who is Bernie Madoff?  Look him up. . . he is in jail right now

Will you buy the car from Bernie Madoff
