# Way OT: Math help for work

I'm working on some pricing that has three variables that all depend on one another:

Variable1: 7 distinct categories

Variable2: 6 distinct categories

Variable3: whole numbers 1-50

What I'm trying to do is look at a months total spend, and calculate how much of the total can be attributed to each variable

Variable1 is non-linear

Variable 2 is a step function

Variable 3 is non linear.

Sorry for wasting mgospace, I'm just thoroughly stumped.
