1 sticker costs $3.
1 bag of 50 stickers costs $20.
Adam needs 54 stickers.
- What is the minimum number of bags that Adam should buy?
- How much will Adam spend?
(a)
Sets of 50 stickers
= 54 ÷ 50
= 1 r 4
Amount that Adam has to spend to buy 4 stickers
= 4 x 3
= $12
To buy 4 stickers at $12 is more expensive than 50 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
