Charlie has some money to buy some stickers.
If he buys 6 stickers, he will have $14 left.
If he buys 9 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
= 9 - 6
= 3
Difference in the amount to pay in both scenarios
= 14 - 2
= 12
Charlie needs $12 to buy 3 extra stickers.
Cost of 3 stickers = $12
Cost of 1 sticker = 12 ÷ 3 = $4
(b)
Amount that he has
= Cost of 6 stickers + 14
= 6 x 4 + 14
= 24 + 14
= $38
Answer(s): (a) $4; (b) $38
