Adam has enough money to buy 6 marbles at $15 each.
If he does not buy the marbles, he can buy 10 stickers with the same amount of money.
- How much does each sticker cost?
- How much more is a marble than a sticker?
(a)
Amount that Adam has
= 6 x 15
= $90
Cost of each sticker

= $9
(b)
Amount that a marble costs more than a sticker
= 15 - 9
= $6
Answer(s): (a) $9; (b) $6
