1 sticker costs $3.
1 bag of 55 stickers costs $10.
Adam needs 56 stickers.
- What is the minimum number of bags that Adam should buy?
- How much will Adam spend?
(a)
Sets of 55 stickers
= 56 ÷ 55
= 1 r 1
Amount that Adam has to spend to buy 1 stickers
= 1 x 3
= $3
To buy 1 stickers at $3 is more expensive than 55 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
