Charlie has some money to buy some stickers.
If he buys 6 stickers, he will have $8 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 - 6
= 6
Difference in the amount to pay in both scenarios
= 8 - 2
= 6
Charlie needs $6 to buy 6 extra stickers.
Cost of 6 stickers = $6
Cost of 1 sticker = 6 ÷ 6 = $1
(b)
Amount that he has
= Cost of 6 stickers + 8
= 6 x 1 + 8
= 6 + 8
= $14
Answer(s): (a) $1; (b) $14
