Adam has some money to buy some stickers.
If he buys 2 stickers, he will have $12 left.
If he buys 6 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
= 6 - 2
= 4
To buy 4 stickers, he needs to use $12 that is left and get an extra of $12.
Difference in the amount to pay in both scenarios
= 12 + 12
= $24
Adam needs $24 to buy 4 extra stickers .
Cost of 4 stickers = $24
Cost of 1 sticker = 24 ÷ 4 = $6
(b)
Amount that he has
= Cost of 2 stickers + 12
= 2 x 6 + 12
= 12 + 12
= $24
Answer(s): (a) $6; (b) $24
