Adam has enough money to buy 2 marbles at $9 each.
If he does not buy the marbles, he can buy 6 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 9
= $18
Cost of each bead

= $3
(b)
Amount that a marble costs more than a bead
= 9 - 3
= $6
Answer(s): (a) $3; (b) $6
