What have you tried? You need to show some effort at a problem before anyone can help you. Them's the rules...

Log (H) = 192 - Log (T)^x

Fits for the first data set, but doesn't fit the problem?

I'm confused and stuck?

You have not given us the entire problem description. Apparently you are supposed to fit this data to some kind of function. Since you are given two points-- (0, 192) and (22, 42), one possibility is to fit this data to a linear equation.

If you are supposed to do this some other way, please specify what that way is.
