Adam has enough money to buy 3 marbles at $15 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 15
= $45
Cost of each bead
= 45 ÷ 9
= $5
(b)
Amount that a marble costs more than a bead
= 15 - 5
= $10
Answer(s): (a) $5; (b) $10
