Adam has enough money to buy 5 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
= 5 x 16
= $80
Cost of each marble
= 80 ÷ 8
= $10
(b)
Amount that a bead costs more than a marble
= 16 - 10
= $6
Answer(s): (a) $10; (b) $6
