Adam has enough money to buy 6 beads at $12 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
= 6 x 12
= $72
Cost of each marble
= 72 ÷ 9
= $8
(b)
Amount that a bead costs more than a marble
= 12 - 8
= $4
Answer(s): (a) $8; (b) $4
