Increase Tex Stack Size How Much Money Will You Get From A Tex Increase?

How much money will you get from a tex increase? - increase tex stack size

I am writing a problem / solution and my test is about obesity in America. One of my solutions would be for the government to the members in the gym give open gym or federal funding people who benefit from it. My question is: How much would a tax increase for the solution to financing is needed, and money you raise from this tax.

Or if someone another solution, I use gyms, free, active lifestyle, health groups and teach young children to school (in the course of health) to obesity.
