Adam has some money to buy some stickers.
If he buys 5 stickers, he will have $22 left.
If he buys 12 stickers, he will have $8 left.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 12 - 5
= 7
Difference in the amount to pay in both scenarios
= 22 - 8
= 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 5 stickers + 22
= 5 x 2 + 22
= 10 + 22
= $32
Answer(s): (a) $2; (b) $32
