Adam has some money to buy some stickers.
If he buys 6 stickers, he will have $8 left.
If he buys 8 stickers, he will need $12 more.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 8 - 6
= 2
To buy 2 stickers, he needs to use $8 that is left and get an extra of $12.
Difference in the amount to pay in both scenarios
= 8 + 12
= $20
Adam needs $20 to buy 2 extra stickers .
Cost of 2 stickers = $20
Cost of 1 sticker = 20 ÷ 2 = $10
(b)
Amount that he has
= Cost of 6 stickers + 8
= 6 x 10 + 8
= 60 + 8
= $68
Answer(s): (a) $10; (b) $68
