1 sticker costs $4.
1 bag of 55 stickers costs $20.
Adam needs 64 stickers.
- What is the minimum number of bags that Adam should buy?
- How much will Adam spend?
(a)
Sets of 55 stickers
= 64 ÷ 55
= 1 r 9
Amount that Adam has to spend to buy 9 stickers
= 9 x 4
= $36
To buy 9 stickers at $36 is more expensive than 55 stickers at $20.
Minimum number of bags that Adam has to buy
= 1 + 1
= 2
(b)
Amount that Adam has to spend on 2 bags
= 2 x 20
= $40
Answer(s): (a) 2; (b) $40
