Bryan has some money to buy some stickers.
If he buys 2 stickers, he will have $13 left.
If he buys 4 stickers, he will have $11 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 4 - 2
= 2
Difference in the amount to pay in both scenarios
= 13 - 11
= 2
Bryan needs $2 to buy 2 extra stickers.
Cost of 2 stickers = $2
Cost of 1 sticker = 2 ÷ 2 = $1
(b)
Amount that he has
= Cost of 2 stickers + 13
= 2 x 1 + 13
= 2 + 13
= $15
Answer(s): (a) $1; (b) $15
