Bryan has some money to buy some stickers.
If he buys 8 stickers, he will have $15 left.
If he buys 11 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
= 11 - 8
= 3
Difference in the amount to pay in both scenarios
= 15 - 12
= 3
Bryan needs $3 to buy 3 extra stickers.
Cost of 3 stickers = $3
Cost of 1 sticker = 3 ÷ 3 = $1
(b)
Amount that he has
= Cost of 8 stickers + 15
= 8 x 1 + 15
= 8 + 15
= $23
Answer(s): (a) $1; (b) $23
