Bryan has some money to buy some stickers.
If he buys 3 stickers, he will have $17 left.
If he buys 6 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
= 6 - 3
= 3
Difference in the amount to pay in both scenarios
= 17 - 5
= 12
Bryan needs $12 to buy 3 extra stickers.
Cost of 3 stickers = $12
Cost of 1 sticker = 12 ÷ 3 = $4
(b)
Amount that he has
= Cost of 3 stickers + 17
= 3 x 4 + 17
= 12 + 17
= $29
Answer(s): (a) $4; (b) $29
