1 button costs $2.
1 box of 10 buttons costs $7.
Adriel has $90.
- What is the maximum number of boxes that Adriel can buy?
- How many buttons does Adriel buy in total?
(a)
Sets of $7 in $90
= 90 ÷ 7
= 12 r 6
Maximum number of boxes that Adriel can buy = 12
(b)
Number of buttons that he can buy with $84
= 12 x 10
= 120
Number of buttons that Adriel can buy with $6
= 6 ÷ 2
= 3
Total number of buttons that Adriel buys
= 120 + 3
= 123
Answer(s): (a) 12; (b) 123
