Bryan has some money to buy some stickers.
If he buys 8 stickers, he will have $20 left.
If he buys 11 stickers, he will have $5 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 11 - 8
= 3
Difference in the amount to pay in both scenarios
= 20 - 5
= 15
Bryan 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 8 stickers + 20
= 8 x 5 + 20
= 40 + 20
= $60
Answer(s): (a) $5; (b) $60
