Alex wants to buy some stickers for 8 students.
Each packet of stickers has 10 stickers.
One packet of stickers costs $9.
- What is the least number of packets that he needs to buy so that each student gets 9 stickers?
- How much does Alex have to spend?
(a)
Number of stickers that Alex needs
= 8 x 9
= 72
Number of packets
= 72 ÷ 10
= 7 r 2
Least number of packets that he needs to buy
= 7 + 1
= 8
(b)
Amount that Alex has to spend
= 8 x 9
= $72
Answer(s): (a) 8; (b) $72
