Bryan has some money to buy some stickers.
If he buys 8 stickers, he will have $19 left.
If he buys 10 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
= 10 - 8
= 2
Difference in the amount to pay in both scenarios
= 19 - 5
= 14
Bryan needs $14 to buy 2 extra stickers.
Cost of 2 stickers = $14
Cost of 1 sticker = 14 ÷ 2 = $7
(b)
Amount that he has
= Cost of 8 stickers + 19
= 8 x 7 + 19
= 56 + 19
= $75
Answer(s): (a) $7; (b) $75
