1 sticker costs $5.
1 packet of 30 stickers costs $25.
Adam needs 32 stickers.
- What is the minimum number of packets that Adam should buy?
- How much will Adam spend?
(a)
Sets of 30 stickers
= 32 ÷ 30
= 1 r 2
Amount that Adam has to spend to buy 2 stickers
= 2 x 5
= $10
To buy 2 stickers at $10 is more expensive than 30 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
