Adam has some money to buy some stickers.
If he buys 2 stickers, he will have $16 left.
If he buys 8 stickers, he will have $10 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 8 - 2
= 6
Difference in the amount to pay in both scenarios
= 16 - 10
= 6
Adam needs $6 to buy 6 extra stickers.
Cost of 6 stickers = $6
Cost of 1 sticker = 6 ÷ 6 = $1
(b)
Amount that he has
= Cost of 2 stickers + 16
= 2 x 1 + 16
= 2 + 16
= $18
Answer(s): (a) $1; (b) $18
