1 stamp costs $2.
1 packet of 8 stamps costs $7.
Ahmad has $90.
- What is the maximum number of packets that Ahmad can buy?
- How many stamps does Ahmad buy in total?
(a)
Sets of $7 in $90
= 90 ÷ 7
= 12 r 6
Maximum number of packets that Ahmad can buy = 12
(b)
Number of stamps that he can buy with $84
= 12 x 8
= 96
Number of stamps that Ahmad can buy with $6
= 6 ÷ 2
= 3
Total number of stamps that Ahmad buys
= 96 + 3
= 99
Answer(s): (a) 12; (b) 99
