Adam has some money to buy some stickers.
If he buys 2 stickers, he will have $10 left.
If he buys 12 stickers, he will need $10 more.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 12 - 2
= 10
To buy 10 stickers, he needs to use $10 that is left and get an extra of $10.
Difference in the amount to pay in both scenarios
= 10 + 10
= $20
Adam needs $20 to buy 10 extra stickers .
Cost of 10 stickers = $20
Cost of 1 sticker = 20 ÷ 10 = $2
(b)
Amount that he has
= Cost of 2 stickers + 10
= 2 x 2 + 10
= 4 + 10
= $14
Answer(s): (a) $2; (b) $14
