Bryan has some money to buy some stickers.
If he buys 7 stickers, he will have $24 left.
If he buys 9 stickers, he will have $10 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 9 - 7
= 2
Difference in the amount to pay in both scenarios
= 24 - 10
= 14
Bryan 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 7 stickers + 24
= 7 x 7 + 24
= 49 + 24
= $73
Answer(s): (a) $7; (b) $73
