1 marble costs $2.
1 box of 5 marbles costs $10.
Alan has $78.
- What is the maximum number of boxes that Alan can buy?
- How many marbles does Alan buy in total?
(a)
Sets of $10 in $78
= 78 ÷ 10
= 7 r 8
Maximum number of boxes that Alan can buy = 7
(b)
Number of marbles that he can buy with $70
= 7 x 5
= 35
Number of marbles that Alan can buy with $8
= 8 ÷ 2
= 4
Total number of marbles that Alan buys
= 35 + 4
= 39
Answer(s): (a) 7; (b) 39
