1 sticker costs $5.
1 packet of 55 stickers costs $20.
Adam needs 59 stickers.
- What is the minimum number of packets that Adam should buy?
- How much will Adam spend?
(a)
Sets of 55 stickers
= 59 ÷ 55
= 1 r 4
Amount that Adam has to spend to buy 4 stickers
= 4 x 5
= $20
To buy 4 stickers at $20 is more expensive than 55 stickers at $20.
Minimum number of packets that Adam has to buy
= 1 + 1
= 2
(b)
Amount that Adam has to spend on 2 packets
= 2 x 20
= $40
Answer(s): (a) 2; (b) $40
