1 sticker costs $2.
1 packet of 35 stickers costs $20.
Adam needs 61 stickers.
- What is the minimum number of packets that Adam should buy?
- How much will Adam spend?
(a)
Sets of 35 stickers
= 61 ÷ 35
= 1 r 26
Amount that Adam has to spend to buy 26 stickers
= 26 x 2
= $52
To buy 26 stickers at $52 is more expensive than 35 stickers at $20.
Minimum number of packets that Adam has to buy
= 1 + 1
= 2
(b)
Amount that Adam has to spend on 2 packets
= 2 x 20
= $40
Answer(s): (a) 2; (b) $40
