Adam has enough money to buy 3 beads at $9 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
= 3 x 9
= $27
Cost of each marble
= 27 ÷ 9
= $3
(b)
Amount that a bead costs more than a marble
= 9 - 3
= $6
Answer(s): (a) $3; (b) $6
