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?

Respuesta :

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
