Ahmad wants to buy some stickers for 15 pupils.
Each packet of stickers has 7 stickers.
One packet of stickers costs $4.
- What is the least number of packets that he needs to buy so that each pupil gets 8 stickers?
- How much does Ahmad have to spend?
(a)
Number of stickers that Ahmad needs
= 15 x 8
= 120
Number of packets
= 120 ÷ 7
= 17 r 1
Least number of packets that he needs to buy
= 17 + 1
= 18
(b)
Amount that Ahmad has to spend
= 18 x 4
= $72
Answer(s): (a) 18; (b) $72
