Yes utility functions (Calculating the utility you gain from items/services you name it).
The basic moduls and functions are not good enough to describe utility gained from every item combined etc.
Heres a pdf about the basics. Its microeconomics 101
yes, utility functions cant tell you HOW much more you prefer one item(s) over another item(s) but only which of the items you prefer.
but it could be cool to construct some function that defined how much more you prefered something over another. Just saying, there is a nobel prize waiting for someone there

Same thing with me. Im not smart enough to figure it out.
Maybe when im done with my grad school i get a better estimation but if people with a phd havent made a model yet im not gonna figure it out
