Adam has enough money to buy 3 marbles at $12 each.
If he does not buy the marbles, he can buy 9 beads with the same amount of money.
- How much does each bead cost?
- How much more is a marble than a bead?
(a)
Amount that Adam has
= 3 x 12
= $36
Cost of each bead
= 36 ÷ 9
= $4
(b)
Amount that a marble costs more than a bead
= 12 - 4
= $8
Answer(s): (a) $4; (b) $8
