Bryan has some money to buy some stickers.
If he buys 2 stickers, he will have $11 left.
If he buys 6 stickers, he will have $7 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 6 - 2
= 4
Difference in the amount to pay in both scenarios
= 11 - 7
= 4
Bryan needs $4 to buy 4 extra stickers.
Cost of 4 stickers = $4
Cost of 1 sticker = 4 ÷ 4 = $1
(b)
Amount that he has
= Cost of 2 stickers + 11
= 2 x 1 + 11
= 2 + 11
= $13
Answer(s): (a) $1; (b) $13
