Adam has enough money to buy 2 marbles at $20 each.
If he does not buy the marbles, he can buy 5 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 20
= $40
Cost of each bead
= 40 ÷ 5
= $8
(b)
Amount that a marble costs more than a bead
= 20 - 8
= $12
Answer(s): (a) $8; (b) $12
