1 sticker costs $2.
1 packet of 20 stickers costs $30.
Adam needs 43 stickers.
- What is the minimum number of packets that Adam should buy?
- How much will Adam spend?
(a)
Sets of 20 stickers
= 43 ÷ 20
= 2 r 3
Minimum number of packets that Adam should buy = 2
(b)
Amount that Adam has to spend to buy 3 stickers
= 3 x 2
= $6
Amount that Adam has to spend on 2 packets
= 2 x 30
= $60
Total amount that Adam has to spend
= 60 + 6
= $66
Answer(s): (a) 2; (b) $66
