c) Suppose a firm wishes to minimize cost C C=rK+wL subject to producing a target level of output Y. The production function is F(K,L). r denotes the rental rate on capital K, while w is the cost of a unit of labour L. i) ii) iii) Set up the Lagrangian for this problem. Interpret the value of the Lagrangian multiplier at the optimum. Use the Envelope Theorem to determine how the minimum cost changes when the wage rises by one unit. Briefly explain what the Envelope Theorem says.

Suppose your company seeks to maximize their production. Maximize your company's production function of: 2A + 4B, subject to the following constraints: DM: 1A 1B < = 750 DL: 1A5B < = 1,000 OH: 1A 1B < = 900 Please graph each constraint on the same graph. Put B on the vertical axis. Label the quantity intercept, for each item, on each constraint. Label the point, on each axis, where the maximized function provides the optimal quantity of each item.

The business venture involves the sale of decorative jewelry cases. It costs the startup $280 to produce 40 decorative jewelry cases a week while it costs $320 to produce 60 decorative cases per week as well. you and your partners are told that the demand, x, for your product is given as a linear function of price, p, where p(x)=15−0.02x Use the information above, to answer the following questions: 1. Given that the break even points are 16 and 634, If the intention is to make at most 800 jewellery cases a week, what range of quantity demanded can the startup ensure a profit is made. 2. Determine the Maximum Profit that can be made by this new business venture.
