Ahmad wants to buy some stickers for 12 pupils.
Each bag of stickers has 7 stickers.
One bag of stickers costs $7.
- What is the least number of bags that he needs to buy so that each pupil gets 3 stickers?
- How much does Ahmad have to spend?
(a)
Number of stickers that Ahmad needs
= 12 x 3
= 36
Number of bags
= 36 ÷ 7
= 5 r 1
Least number of bags that he needs to buy
= 5 + 1
= 6
(b)
Amount that Ahmad has to spend
= 6 x 7
= $42
Answer(s): (a) 6; (b) $42
