Adam has enough money to buy 3 beads at $3 each.
If he does not buy the beads, he can buy 9 marbles with the same amount of money.
- How much does each marble cost?
- How much more is a bead than a marble?
(a)
Amount that Adam has
= 3 x 3
= $9
Cost of each marble

= $1
(b)
Amount that a bead costs more than a marble
= 3 - 1
= $2
Answer(s): (a) $1; (b) $2
