Charlie has some money to buy some stickers.
If he buys 8 stickers, he will have $11 left.
If he buys 10 stickers, he will have $3 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 10 - 8
= 2
Difference in the amount to pay in both scenarios
= 11 - 3
= 8
Charlie needs $8 to buy 2 extra stickers.
Cost of 2 stickers = $8
Cost of 1 sticker = 8 ÷ 2 = $4
(b)
Amount that he has
= Cost of 8 stickers + 11
= 8 x 4 + 11
= 32 + 11
= $43
Answer(s): (a) $4; (b) $43
