Charlie has some money to buy some stickers.
If he buys 8 stickers, he will have $14 left.
If he buys 12 stickers, he will have $2 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 12 - 8
= 4
Difference in the amount to pay in both scenarios
= 14 - 2
= 12
Charlie needs $12 to buy 4 extra stickers.
Cost of 4 stickers = $12
Cost of 1 sticker = 12 ÷ 4 = $3
(b)
Amount that he has
= Cost of 8 stickers + 14
= 8 x 3 + 14
= 24 + 14
= $38
Answer(s): (a) $3; (b) $38
