1 button costs $2.
1 packet of 10 buttons costs $12.
Ali has $64.
- What is the maximum number of packets that Ali can buy?
- How many buttons does Ali buy in total?
(a)
Sets of $12 in $64
= 64 ÷ 12
= 5 r 4
Maximum number of packets that Ali can buy = 5
(b)
Number of buttons that he can buy with $60
= 5 x 10
= 50
Number of buttons that Ali can buy with $4
= 4 ÷ 2
= 2
Total number of buttons that Ali buys
= 50 + 2
= 52
Answer(s): (a) 5; (b) 52
