Charlie has some money to buy some stickers.
If he buys 2 stickers, he will have $20 left.
If he buys 5 stickers, he will have $8 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 5 - 2
= 3
Difference in the amount to pay in both scenarios
= 20 - 8
= 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 2 stickers + 20
= 2 x 4 + 20
= 8 + 20
= $28
Answer(s): (a) $4; (b) $28
