Question

William bought a new backpack at the store when they were having a 40% percent off sale. If the regular price of the backpack was $35 how much did William pay with the discount?

Answer 1

He payed 21 dollars rather than the original 35.

Answer 2

Answer: $21

Since it is 40% off, then we need to find 60% of the regular price.

To solve: 
0.6•35=21
