1 sticker costs $4.
1 box of 40 stickers costs $10.
Adam needs 82 stickers.
- What is the minimum number of boxs that Adam should buy?
- How much will Adam spend?
(a)
Sets of 40 stickers
= 82 ÷ 40
= 2 r 2
Amount that Adam has to spend to buy 2 stickers
= 2 x 4
= $8
To buy 2 stickers at $8 is more expensive than 40 stickers at $10.
Minimum number of boxs that Adam has to buy
= 2 + 1
= 3
(b)
Amount that Adam has to spend on 3 boxs
= 3 x 10
= $30
Answer(s): (a) 3; (b) $30
