Bryan has some money to buy some stickers.
If he buys 10 stickers, he will have $14 left.
If he buys 17 stickers, he will have $7 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 17 - 10
= 7
Difference in the amount to pay in both scenarios
= 14 - 7
= 7
Bryan needs $7 to buy 7 extra stickers.
Cost of 7 stickers = $7
Cost of 1 sticker = 7 ÷ 7 = $1
(b)
Amount that he has
= Cost of 10 stickers + 14
= 10 x 1 + 14
= 10 + 14
= $24
Answer(s): (a) $1; (b) $24
