Adam has some money to buy 10 stickers
but he buys only 5 stickers and has $15 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Number of stickers that Adam has not bought
= 10 - 5
= 5
Cost of 5 stickers = $15
Cost of 1 sticker = 15 ÷ 5 = $3
(b)
Amount that Adam has
= Cost of 10 stickers
= 10 x 3
= $30
Answer(s): (a) $3; (b) $30
