Final answer:
Cam has 37 stickers, and Dan has 74 stickers.
Step-by-step explanation:
Let's assume that Cam has x stickers.
According to the given information, Dan has twice as many stickers as Cam, so Dan has 2x stickers.
If Dan gives Cam 15 stickers, he will have 22 more stickers than Cam.
So, we can set up the equation: 2x - 15 = x + 22.
Solving this equation, we get: x = 37.
Therefore, Cam has 37 stickers and Dan has 74 stickers.
