1 sticker costs $3.
1 packet of 55 stickers costs $30.
Adam needs 87 stickers.
- What is the minimum number of packets that Adam should buy?
- How much will Adam spend?
(a)
Sets of 55 stickers
= 87 ÷ 55
= 1 r 32
Amount that Adam has to spend to buy 32 stickers
= 32 x 3
= $96
To buy 32 stickers at $96 is more expensive than 55 stickers at $30.
Minimum number of packets that Adam has to buy
= 1 + 1
= 2
(b)
Amount that Adam has to spend on 2 packets
= 2 x 30
= $60
Answer(s): (a) 2; (b) $60
