Mrs. Wise bought 3 lb of apples at $4 per lb. The following day there was 20% discount so she bought another 5 lb. What was the average price for all apples she bought?
3 lb x$4 = $12 20% discount is .20 x $4 = $0.80 $4 - $0.80 = $3.20 5 lb x $3.20= $16 She spent a total of $28. She bought 8 pounds total. $28/8= $3.50/pound average
