1 sticker costs $3.
1 packet of 40 stickers costs $30.
Adam needs 76 stickers.
- What is the minimum number of packets that Adam should buy?
- How much will Adam spend?
(a)
Sets of 40 stickers
= 76 ÷ 40
= 1 r 36
Amount that Adam has to spend to buy 36 stickers
= 36 x 3
= $108
To buy 36 stickers at $108 is more expensive than 40 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
