1 sticker costs $2.
1 packet of 20 stickers costs $30.
Adam needs 84 stickers.
- What is the minimum number of packets that Adam should buy?
- How much will Adam spend?
(a)
Sets of 20 stickers
= 84 ÷ 20
= 4 r 4
Minimum number of packets that Adam should buy = 4
(b)
Amount that Adam has to spend to buy 4 stickers
= 4 x 2
= $8
Amount that Adam has to spend on 4 packets
= 4 x 30
= $120
Total amount that Adam has to spend
= 120 + 8
= $128
Answer(s): (a) 4; (b) $128
