Adam has some money to buy 10 stickers
but he buys only 6 stickers and has $20 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Number of stickers that Adam has not bought
= 10 - 6

Cost of 4 stickers = $20
Cost of 1 sticker = 20 ÷ 4 = $5

= Cost of 10 stickers
= 10 x 5
= $50
Answer(s): (a) $5; (b) $50
