1 sticker costs $2.
1 box of 35 stickers costs $10.
Adam needs 39 stickers.
- What is the minimum number of boxs that Adam should buy?
- How much will Adam spend?
(a)
Sets of 35 stickers
= 39 ÷ 35
= 1 r 4
Amount that Adam has to spend to buy 4 stickers
= 4 x 2
= $8
To buy 4 stickers at $8 is more expensive than 35 stickers at $10.
Minimum number of boxs that Adam has to buy
= 1 + 1
= 2
(b)
Amount that Adam has to spend on 2 boxs
= 2 x 10
= $20
Answer(s): (a) 2; (b) $20
