Adam has enough money to buy 4 marbles at $10 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
= 4 x 10
= $40
Cost of each bead
= 40 ÷ 10
= $4
(b)
Amount that a marble costs more than a bead
= 10 - 4
= $6
Answer(s): (a) $4; (b) $6
