Charlie has some money to buy some stickers.
If he buys 2 stickers, he will have $22 left.
If he buys 8 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
= 8 - 2
= 6
Difference in the amount to pay in both scenarios
= 22 - 10
= 12
Charlie needs $12 to buy 6 extra stickers.
Cost of 6 stickers = $12
Cost of 1 sticker = 12 ÷ 6 = $2
(b)
Amount that he has
= Cost of 2 stickers + 22
= 2 x 2 + 22
= 4 + 22
= $26
Answer(s): (a) $2; (b) $26
