Adam has enough money to buy 2 beads at $18 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
= 2 x 18
= $36
Cost of each marble
= 36 ÷ 9
= $4
(b)
Amount that a bead costs more than a marble
= 18 - 4
= $14
Answer(s): (a) $4; (b) $14
