Charlie has some money to buy some stickers.
If he buys 6 stickers, he will have $18 left.
If he buys 8 stickers, he will have $4 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 8 - 6
= 2
Difference in the amount to pay in both scenarios
= 18 - 4
= 14
Charlie needs $14 to buy 2 extra stickers.
Cost of 2 stickers = $14
Cost of 1 sticker = 14 ÷ 2 = $7
(b)
Amount that he has
= Cost of 6 stickers + 18
= 6 x 7 + 18
= 42 + 18
= $60
Answer(s): (a) $7; (b) $60
