Bryan has some money to buy some stickers.
If he buys 6 stickers, he will have $19 left.
If he buys 11 stickers, he will have $9 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 11 - 6
= 5
Difference in the amount to pay in both scenarios
= 19 - 9
= 10
Bryan needs $10 to buy 5 extra stickers.
Cost of 5 stickers = $10
Cost of 1 sticker = 10 ÷ 5 = $2
(b)
Amount that he has
= Cost of 6 stickers + 19
= 6 x 2 + 19
= 12 + 19
= $31
Answer(s): (a) $2; (b) $31
