1 sticker costs $4.
1 packet of 35 stickers costs $10.
Adam needs 62 stickers.
- What is the minimum number of packets that Adam should buy?
- How much will Adam spend?
(a)
Sets of 35 stickers
= 62 ÷ 35
= 1 r 27
Amount that Adam has to spend to buy 27 stickers
= 27 x 4
= $108
To buy 27 stickers at $108 is more expensive than 35 stickers at $10.
Minimum number of packets that Adam has to buy
= 1 + 1
= 2
(b)
Amount that Adam has to spend on 2 packets
= 2 x 10
= $20
Answer(s): (a) 2; (b) $20
