56. Christy and Adam went to Wal-mart to buy a few items. They bought a pack of

chicken for $12. 97, a gallon of milk for $4. 97 , 4 bags of chips for 2 for $5. 00, and

10 Sam's Choice 2 liter drinks for $. 67 each. When they got to the register the clerk

told them that the chicken was on sale for 30% off the price. How much did they

spend in all?
