1 eraser costs $2.
1 bag of 9 erasers costs $10.
Adam has $88.
- What is the maximum number of bags that Adam can buy?
- How many erasers does Adam buy in total?
(a)
Sets of $10 in $88
= 88 ÷ 10
= 8 r 8
Maximum number of bags that Adam can buy = 8
(b)
Number of erasers that he can buy with $80
= 8 x 9
= 72
Number of erasers that Adam can buy with $8
= 8 ÷ 2
= 4
Total number of erasers that Adam buys
= 72 + 4
= 76
Answer(s): (a) 8; (b) 76
