1 sticker costs $1.
1 packet of 30 stickers costs $20.
Adam needs 64 stickers.
- What is the minimum number of packets that Adam should buy?
- How much will Adam spend?
(a)
Sets of 30 stickers
= 64 ÷ 30
= 2 r 4
Minimum number of packets that Adam should buy = 2
(b)
Amount that Adam has to spend to buy 4 stickers
= 4 x 1
= $4
Amount that Adam has to spend on 2 packets
= 2 x 20
= $40
Total amount that Adam has to spend
= 40 + 4
= $44
Answer(s): (a) 2; (b) $44
