1 sticker costs $3.
1 packet of 45 stickers costs $25.
Adam needs 80 stickers.
- What is the minimum number of packets that Adam should buy?
- How much will Adam spend?
(a)
Sets of 45 stickers
= 80 ÷ 45
= 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 45 stickers at $25.
Minimum number of packets that Adam has to buy
= 1 + 1
= 2
(b)
Amount that Adam has to spend on 2 packets
= 2 x 25
= $50
Answer(s): (a) 2; (b) $50
