Adam has enough money to buy 5 beads at $7 each.
If he does not buy the beads, he can buy 7 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 7
= $35
Cost of each marble

= $5
(b)
Amount that a bead costs more than a marble
= 7 - 5
= $2
Answer(s): (a) $5; (b) $2
