1 button costs $2.
1 box of 7 buttons costs $5.
Alex has $94.
- What is the maximum number of boxes that Alex can buy?
- How many buttons does Alex buy in total?
(a)
Sets of $5 in $94
= 94 ÷ 5
= 18 r 4
Maximum number of boxes that Alex can buy = 18
(b)
Number of buttons that he can buy with $90
= 18 x 7
= 126
Number of buttons that Alex can buy with $4
= 4 ÷ 2
= 2
Total number of buttons that Alex buys
= 126 + 2
= 128
Answer(s): (a) 18; (b) 128
