Adam has enough money to buy 3 beads at $15 each.
If he does not buy the beads, he can buy 5 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 15
= $45
Cost of each marble
= 45 ÷ 5
= $9
(b)
Amount that a bead costs more than a marble
= 15 - 9
= $6
Answer(s): (a) $9; (b) $6
