1 eraser costs $2.
1 bag of 7 erasers costs $5.
Amadeus has $69.
- What is the maximum number of bags that Amadeus can buy?
- How many erasers does Amadeus buy in total?
(a)
Sets of $5 in $69
= 69 ÷ 5
= 13 r 4
Maximum number of bags that Amadeus can buy = 13
(b)
Number of erasers that he can buy with $65
= 13 x 7
= 91
Number of erasers that Amadeus can buy with $4
= 4 ÷ 2
= 2
Total number of erasers that Amadeus buys
= 91 + 2
= 93
Answer(s): (a) 13; (b) 93
