posted by Calie .
I have the equation 3f+2.50h=240 and I want to make a table of values with at least five possible combinations. How do I determine which combinations I should use?

You can pick any five you want.
How about h  20, 15, 0, 15 and 20?
Solve for the f value in each case.
For example, if h = 0, f = 80
