Adam has some money to buy some stickers.
If he buys 3 stickers, he will have $16 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 - 3
= 3
Difference in the amount to pay in both scenarios
= 16 - 7
= 9
Adam needs $9 to buy 3 extra stickers.
Cost of 3 stickers = $9
Cost of 1 sticker = 9 ÷ 3 = $3
(b)
Amount that he has
= Cost of 3 stickers + 16
= 3 x 3 + 16
= 9 + 16
= $25
Answer(s): (a) $3; (b) $25
