The answer is 10 cookies. All you have to do is subtract 6 from 15, and then add one to your previous answer. Finally, you have your answer!
Hope this helps! :D
First you gotta find out what this is:

Then you gotta figure out what this is too:

=
Once you figure that out you must divide:

And the answer of that equation will be the answer to the problem of how many times bigger the capacity of the of the Madison square Garden in NY than the typical movie theater!
Hope it helps Good Luck! ( If I did anything wrong please let me know and Ill fix it :) )
I'm pretty sure that this is a trick question, the answer is 61%.
The forward differences for this data is 1, 1, 1, 1, 1, 1 (since 10 - 9 = 1, 11 - 10 = 1, etc). Since we only need one iteration of differences, a linear polynomial will fit the data exactly.
36% of 24..... or 0.36 times 24= 8.64
22% of 24......or 0.22 times 24= 5.28
8.64-5.28= 3.36. D.
