Adam has some money to buy some stickers.
If he buys 2 stickers, he will have $27 left.
If he buys 9 stickers, he will have $13 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 9 - 2
= 7
Difference in the amount to pay in both scenarios
= 27 - 13
= 14
Adam needs $14 to buy 7 extra stickers.
Cost of 7 stickers = $14
Cost of 1 sticker = 14 ÷ 7 = $2
(b)
Amount that he has
= Cost of 2 stickers + 27
= 2 x 2 + 27
= 4 + 27
= $31
Answer(s): (a) $2; (b) $31
