A firm sells its product in two different markets. The inverse demand in market A is PA = 72 - 5QA and in market B, it is PB = 60 - 3QB. It has fixed costs of 72. Each unit it produces costs 12, Le, marginal cost equals 12. To maximize profits, what quantities of output will be sold in each market and what will total profits be? What type of function is the utility function expressed as u(x,y)=30lnx + y? Also, how would you go about deriving the demand for x and y in this function
