Adam has some money to buy some stickers.
If he buys 6 stickers, he will have $8 left.
If he buys 10 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
= 10 - 6
= 4
To buy 4 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 4 extra stickers .
Cost of 4 stickers = $16
Cost of 1 sticker = 16 ÷ 4 = $4
(b)
Amount that he has
= Cost of 6 stickers + 8
= 6 x 4 + 8
= 24 + 8
= $32
Answer(s): (a) $4; (b) $32
