a store purchased a DVD for $12.00 and sold it to a customer for 50% more than the purchase price. the customer was a 7% tax when the DVD was sold. what was the customer's total cost for the DVD
50/100 12 = 600/100= 6
12+6= 18( the price without the tax)
7/100 18=126/100 = 1.26
18 + 1.26 = 19.26 $ ( total cost)
