Question

On Monday Mrs. Wise bought 3 lbs of apples at $4 per lb. On Tuesday, apples were on sale for 20% off so she bought another 5 lbs. What was the average price for all apples Mrs. Wise bought?

Answer 1

to find 20% off you multiply .
.2 • 4 = .8 then you subtract .8 from 4
4 - .8 = 3.2
then you multiply the 5 Ibs by 3.2 to get 16 then you add the total of 3 Ibs which is 12 and the total of the 5 Ins which is 16 and you get the total 28 then divide by 2 which is 14 so the average price is $14 for all the apples
