Bryan has some money to buy some stickers.
If he buys 7 stickers, he will have $25 left.
If he buys 9 stickers, he will have $13 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 9 - 7
= 2
Difference in the amount to pay in both scenarios
= 25 - 13
= 12
Bryan needs $12 to buy 2 extra stickers.
Cost of 2 stickers = $12
Cost of 1 sticker = 12 ÷ 2 = $6
(b)
Amount that he has
= Cost of 7 stickers + 25
= 7 x 6 + 25
= 42 + 25
= $67
Answer(s): (a) $6; (b) $67
