Hello!
First you have to find what percent like action movies with the data you have
You add all the numbers up
80 + 160 + 200 + 360 = 800
Now you divide the amount that like action by the total amount of people that answered
160 / 800 = 0.2
Now you multiply this by 3200 to see how many would say action
3200 * 0.2 = 640
The answer is 640
Hope this helps!
