1 eraser costs $3.
1 bag of 5 erasers costs $13.
Alistair has $87.
- What is the maximum number of bags that Alistair can buy?
- How many erasers does Alistair buy in total?
(a)
Sets of $13 in $87
= 87 ÷ 13
= 6 r 9
Maximum number of bags that Alistair can buy = 6
(b)
Number of erasers that he can buy with $78
= 6 x 5
= 30
Number of erasers that Alistair can buy with $9
= 9 ÷ 3
= 3
Total number of erasers that Alistair buys
= 30 + 3
= 33
Answer(s): (a) 6; (b) 33
