Bryan has some money to buy some stickers.
If he buys 9 stickers, he will have $8 left.
If he buys 11 stickers, he will have $2 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 11 - 9
= 2
Difference in the amount to pay in both scenarios
= 8 - 2
= 6
Bryan needs $6 to buy 2 extra stickers.
Cost of 2 stickers = $6
Cost of 1 sticker = 6 ÷ 2 = $3
(b)
Amount that he has
= Cost of 9 stickers + 8
= 9 x 3 + 8
= 27 + 8
= $35
Answer(s): (a) $3; (b) $35
