I believe that fast food restaurants show short run production function because of the one fixed input, capital. But, I need to elaborate more and produce the production function equation Q=F (L,K,M...) Can you please help?
Also on the fast food restaurant like McDonalds, fixed and variable cost are fixed is capital, building, stove, refrigerators..... and for variable, wages, and materials, hamburgers, potatoes.... Is that correct?
