Question

You bought your first car for $3,000 and make payments of $150 each month. Letting B represent the balance (what still needs to be paid), which function rule represents how much money is still owed (the balance) after m months?

B(m) = 3000m

B(m) = 3000 + 150m

B(m) = 3000 - 150m

B(m) = -3000 - 150m

Answer 1

Answer B: B(m) = 3000 - 150m

Explanation:

pay attention to the $3000 and making payments for $150 a month. Since $3000 is a positive number and you are trying to pay it off, you subtract off of it.

So subtract $150 to get your answer.
