Adam has some money to buy some stickers.
If he buys 8 stickers, he will have $8 left.
If he buys 16 stickers, he will need $8 more.
- How much does each sticker cost?
- How much money does he have?
(a)
Difference in the number of stickers in both scenarios
= 16 - 8
= 8
To buy 8 stickers, he needs to use $8 that is left and get an extra of $8.
Difference in the amount to pay in both scenarios
= 8 + 8
= $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 8 stickers + 8
= 8 x 2 + 8
= 16 + 8
= $24
Answer(s): (a) $2; (b) $24
