Adam has some money to buy some stickers.
If he buys 5 stickers, he will have $11 left.
If he buys 14 stickers, he will have $2 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 14 - 5
= 9
Difference in the amount to pay in both scenarios
= 11 - 2
= 9
Adam needs $9 to buy 9 extra stickers.
Cost of 9 stickers = $9
Cost of 1 sticker = 9 ÷ 9 = $1
(b)
Amount that he has
= Cost of 5 stickers + 11
= 5 x 1 + 11
= 5 + 11
= $16
Answer(s): (a) $1; (b) $16
