Adam has enough money to buy 3 beads at $16 each.
If he does not buy the beads, he can buy 8 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 16
= $48
Cost of each marble
= 48 ÷ 8
= $6
(b)
Amount that a bead costs more than a marble
= 16 - 6
= $10
Answer(s): (a) $6; (b) $10
