Adam has enough money to buy 2 marbles at $15 each.
If he does not buy the marbles, he can buy 10 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
= 2 x 15
= $30
Cost of each bead
= 30 ÷ 10
= $3
(b)
Amount that a marble costs more than a bead
= 15 - 3
= $12
Answer(s): (a) $3; (b) $12
