Charlie has some money to buy some stickers.
If he buys 9 stickers, he will have $24 left.
If he buys 16 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
= 16 - 9
= 7
Difference in the amount to pay in both scenarios
= 24 - 10
= 14
Charlie needs $14 to buy 7 extra stickers.
Cost of 7 stickers = $14
Cost of 1 sticker = 14 ÷ 7 = $2
(b)
Amount that he has
= Cost of 9 stickers + 24
= 9 x 2 + 24
= 18 + 24
= $42
Answer(s): (a) $2; (b) $42
