Adam has some money to buy some stickers.
If he buys 8 stickers, he will have $22 left.
If he buys 10 stickers, he will have $10 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 10 - 8
= 2
Difference in the amount to pay in both scenarios
= 22 - 10
= 12
Adam needs $12 to buy 2 extra stickers.
Cost of 2 stickers = $12
Cost of 1 sticker = 12 ÷ 2 = $6
(b)
Amount that he has
= Cost of 8 stickers + 22
= 8 x 6 + 22
= 48 + 22
= $70
Answer(s): (a) $6; (b) $70
