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
