Adam has some money to buy some stickers.
If he buys 3 stickers, he will have $18 left.
If he buys 6 stickers, he will have $12 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
= 18 - 12
= 6
Adam needs $6 to buy 3 extra stickers.
Cost of 3 stickers = $6
Cost of 1 sticker = 6 ÷ 3 = $2
(b)
Amount that he has
= Cost of 3 stickers + 18
= 3 x 2 + 18
= 6 + 18
= $24
Answer(s): (a) $2; (b) $24
