1 sticker costs $2.
1 packet of 60 stickers costs $20.
Adam needs 68 stickers.
- What is the minimum number of packets that Adam should buy?
- How much will Adam spend?
(a)
Sets of 60 stickers
= 68 ÷ 60
= 1 r 8
Amount that Adam has to spend to buy 8 stickers
= 8 x 2
= $16
To buy 8 stickers at $16 is more expensive than 60 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
