Adam has some money to buy some stickers.
If he buys 2 stickers, he will have $16 left.
If he buys 4 stickers, he will have $6 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
= 16 - 6
= 10
Adam needs $10 to buy 2 extra stickers.
Cost of 2 stickers = $10
Cost of 1 sticker = 10 ÷ 2 = $5
(b)
Amount that he has
= Cost of 2 stickers + 16
= 2 x 5 + 16
= 10 + 16
= $26
Answer(s): (a) $5; (b) $26
