Adam has enough money to buy 7 marbles at $9 each.
If he does not buy the marbles, he can buy 9 beads with the same amount of money.
- How much does each bead cost?
- How much more is a marble than a bead?
(a)
Amount that Adam has
= 7 x 9
= $63
Cost of each bead
= 63 ÷ 9
= $7
(b)
Amount that a marble costs more than a bead
= 9 - 7
= $2
Answer(s): (a) $7; (b) $2
