At the mall, they sell CDs for 3 dollars each if you pay a one-time fee of 99 dollars. At the CD Store, they offer 12 free CDs but charge 12 dollars for each additional CD. How many CDs must you buy so that you will pay the same price at both places?
m = 99 + 3x s = 12x m = s when 12x = 99 + 3x 9x = 99 x = 11
