1 eraser costs $3.
1 packet of 5 erasers costs $15.
Andrew has $87.
- What is the maximum number of packets that Andrew can buy?
- How many erasers does Andrew buy in total?
(a)
Sets of $15 in $87
= 87 ÷ 15
= 5 r 12
Maximum number of packets that Andrew can buy = 5
(b)
Number of erasers that he can buy with $75
= 5 x 5
= 25
Number of erasers that Andrew can buy with $12
= 12 ÷ 3
= 4
Total number of erasers that Andrew buys
= 25 + 4
= 29
Answer(s): (a) 5; (b) 29
