Adam has enough money to buy 2 stickers at $20 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
= 2 x 20
= $40
Cost of each marble
= 40 ÷ 10
= $4
(b)
Amount that a sticker costs more than a marble
= 20 - 4
= $16
Answer(s): (a) $4; (b) $16
