1 sticker costs $2.
1 packet of 15 stickers costs $20.
Adam needs 78 stickers.
- What is the minimum number of packets that Adam should buy?
- How much will Adam spend?
(a)
Sets of 15 stickers
= 78 ÷ 15
= 5 r 3
Minimum number of packets that Adam should buy = 5
(b)
Amount that Adam has to spend to buy 3 stickers
= 3 x 2
= $6
Amount that Adam has to spend on 5 packets
= 5 x 20
= $100
Total amount that Adam has to spend
= 100 + 6
= $106
Answer(s): (a) 5; (b) $106
