1 sticker costs $2.
1 bag of 45 stickers costs $10.
Adam needs 64 stickers.
- What is the minimum number of bags that Adam should buy?
- How much will Adam spend?
(a)
Sets of 45 stickers
= 64 ÷ 45
= 1 r 19
Amount that Adam has to spend to buy 19 stickers
= 19 x 2
= $38
To buy 19 stickers at $38 is more expensive than 45 stickers at $10.
Minimum number of bags that Adam has to buy
= 1 + 1
= 2
(b)
Amount that Adam has to spend on 2 bags
= 2 x 10
= $20
Answer(s): (a) 2; (b) $20
