1 sticker costs $5.
1 packet of 35 stickers costs $15.
Adam needs 41 stickers.
- What is the minimum number of packets that Adam should buy?
- How much will Adam spend?
(a)
Sets of 35 stickers
= 41 ÷ 35
= 1 r 6
Amount that Adam has to spend to buy 6 stickers
= 6 x 5
= $30
To buy 6 stickers at $30 is more expensive than 35 stickers at $15.
Minimum number of packets that Adam has to buy
= 1 + 1
= 2
(b)
Amount that Adam has to spend on 2 packets
= 2 x 15
= $30
Answer(s): (a) 2; (b) $30
