Answer:
297 baseball cards
Explanation:
If you multiply 2 by 11, you will get 22. Since his sister gives him 22 every month, and they are twelve months in a year, you must take 22 x 12. This gets you 264.
Next you must take 11 x 3, getting you 33. Now you have to take 33 plus the 264, which gets you 297 a year.
