1 sticker costs $5.
1 bag of 30 stickers costs $10.
Adam needs 68 stickers.
- What is the minimum number of bags that Adam should buy?
- How much will Adam spend?
(a)
Sets of 30 stickers
= 68 ÷ 30
= 2 r 8
Amount that Adam has to spend to buy 8 stickers
= 8 x 5
= $40
To buy 8 stickers at $40 is more expensive than 30 stickers at $10.
Minimum number of bags that Adam has to buy
= 2 + 1
= 3
(b)
Amount that Adam has to spend on 3 bags
= 3 x 10
= $30
Answer(s): (a) 3; (b) $30
