Bryan has some money to buy some stickers.
If he buys 5 stickers, he will have $10 left.
If he buys 9 stickers, he will have $6 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 9 - 5
= 4
Difference in the amount to pay in both scenarios
= 10 - 6
= 4
Bryan needs $4 to buy 4 extra stickers.
Cost of 4 stickers = $4
Cost of 1 sticker = 4 ÷ 4 = $1
(b)
Amount that he has
= Cost of 5 stickers + 10
= 5 x 1 + 10
= 5 + 10
= $15
Answer(s): (a) $1; (b) $15
