1 sticker costs $4.
1 packet of 60 stickers costs $30.
Adam needs 67 stickers.
- What is the minimum number of packets that Adam should buy?
- How much will Adam spend?
(a)
Sets of 60 stickers
= 67 ÷ 60
= 1 r 7
Amount that Adam has to spend to buy 7 stickers
= 7 x 4
= $28
To buy 7 stickers at $28 is more expensive than 60 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
