1 sticker costs $3.
1 bag of 50 stickers costs $20.
Adam needs 85 stickers.
- What is the minimum number of bags that Adam should buy?
- How much will Adam spend?
(a)
Sets of 50 stickers
= 85 ÷ 50
= 1 r 35
Amount that Adam has to spend to buy 35 stickers
= 35 x 3
= $105
To buy 35 stickers at $105 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
