1 eraser costs $2.
1 packet of 9 erasers costs $10.
Alfred has $98.
- What is the maximum number of packets that Alfred can buy?
- How many erasers does Alfred buy in total?
(a)
Sets of $10 in $98
= 98 ÷ 10
= 9 r 8
Maximum number of packets that Alfred can buy = 9
(b)
Number of erasers that he can buy with $90
= 9 x 9
= 81
Number of erasers that Alfred can buy with $8
= 8 ÷ 2
= 4
Total number of erasers that Alfred buys
= 81 + 4
= 85
Answer(s): (a) 9; (b) 85
