Adam has some money to buy some stickers.
If he buys 2 stickers, he will have $6 left.
If he buys 10 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
= 10 - 2
= 8
To buy 8 stickers, he needs to use $6 that is left and get an extra of $10.
Difference in the amount to pay in both scenarios
= 6 + 10
= $16
Adam needs $16 to buy 8 extra stickers .
Cost of 8 stickers = $16
Cost of 1 sticker = 16 ÷ 8 = $2
(b)
Amount that he has
= Cost of 2 stickers + 6
= 2 x 2 + 6
= 4 + 6
= $10
Answer(s): (a) $2; (b) $10
