Charlie has some money to buy 10 stickers
but he buys only 4 stickers and has $12 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Number of stickers that Charlie has not bought
= 10 - 4
= 6
Cost of 6 stickers = $12
Cost of 1 sticker = 12 ÷ 6 = $2
(b)
Amount that Charlie has
= Cost of 10 stickers
= 10 x 2
= $20
Answer(s): (a) $2; (b) $20
