Adam has enough money to buy 8 beads at $10 each.
If he does not buy the beads, he can buy 10 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
= 8 x 10
= $80
Cost of each marble
= 80 ÷ 10
= $8
(b)
Amount that a bead costs more than a marble
= 10 - 8
= $2
Answer(s): (a) $8; (b) $2
