Adam has enough money to buy 6 stickers at $15 each.
If he does not buy the stickers, he can buy 10 marbles with the same amount of money.
- How much does each marble cost?
- How much more is a sticker than a marble?
(a)
Amount that Adam has
= 6 x 15
= $90
Cost of each marble
= 90 ÷ 10
= $9
(b)
Amount that a sticker costs more than a marble
= 15 - 9
= $6
Answer(s): (a) $9; (b) $6
