1 bead costs $2.
1 bag of 9 beads costs $7.
Alan has $69.
- What is the maximum number of bags that Alan can buy?
- How many beads does Alan buy in total?
(a)
Sets of $7 in $69
= 69 ÷ 7
= 9 r 6
Maximum number of bags that Alan can buy = 9
(b)
Number of beads that he can buy with $63
= 9 x 9
= 81
Number of beads that Alan can buy with $6
= 6 ÷ 2
= 3
Total number of beads that Alan buys
= 81 + 3
= 84
Answer(s): (a) 9; (b) 84
