Charlie has some money to buy some stickers.
If he buys 2 stickers, he will have $27 left.
If he buys 5 stickers, he will have $12 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
= 27 - 12
= 15
Charlie needs $15 to buy 3 extra stickers.
Cost of 3 stickers = $15
Cost of 1 sticker = 15 ÷ 3 = $5
(b)
Amount that he has
= Cost of 2 stickers + 27
= 2 x 5 + 27
= 10 + 27
= $37
Answer(s): (a) $5; (b) $37
