Ajax, Inc. Assembles gadgets. it can make each gadget either by hand or with a special gadget-making machine. each gadget can be assembled in 15 minutes by a worker or in 5 by a machine. the firm can also choose to make some by hand and some by machine. both are perfect substitutes and they are the only inputs required for production.

a) write down the firm's production function. Let G be number of gadgets assembled, M the number of hours the machine is used, and L the number of hours of labor.

b) say that it costs $30 per hour for the machine and $10 per hour for a worker. graphically represent the cost minimizing output if the firm wants to produce 120 gadgets.

c) what are the cost minimizing input quantities if it costs the firm $30 an hour for the machine and $10 an hour for a worker?

d) derive the expression for the long-run total cost that the firm incurs as a function of q. represent this in a diagram

The simple circuit board can be produced either mechanical or by hand. The hand method required $12 of material and takes 2.8 hours/unit with a labor cost of $9/hour. The equipment has a fixed cost rate of $120,000/year and variable costs of $24.50/unit. The customer requires 12,000 units.   1. If the equipment can be used for other products when not producing these units, which process is the least costly? 2. What if the equipment could only be used for production...

Jenna's Farm Market assembles beautiful hanging flower baskets that they sell for $25 each. They make and sell 1,000 per season. The variable cost of the baskets is $13.50. Fixed costs are $2 per basket. Assorted Growers, a local flower supplier, has offered to supply the 1,000 hanging flower baskets that Jenna's will need for the upcoming spring/summer season. If Jenna's decides to buy the flower baskets instead of making them, they could avoid 40% of the fixed cost per...

Goop Inc. needs to order a raw material to make a special polymer. The demand for the polymer is forecasted to be normally distributed with a mean of 250 gallons and a standard deviation of 100 gallons. Goop sells the polymer for $25 per gallon. Goop purchases raw material for $10 per gallon and must spend $5 per gallon to dispose of all unused raw material due to government regulations. (One gallon of raw material yields one gallon of polymer.)...

You can make a snowball by packing snow together using hand pressure. The effect of this pressure increase is to partially liquefy the ice, which then re-freezes to hold the snow together. By comparing the phase diagrams of water and CO2, determine whether it is possible to make analogous "dry ice balls."

For each of the following functions, find the extreme value of z (this can be either max or min), subject to a given constraint by the method of direct substitution. (a) z = xy, subject to the constraint x2 + y2 = 16 (Note that there are four solutions.) (b) z = 3x2 − 10xy + 12y2 , subject to the constraint y = 20 − 1/2 x (c) z = xy, subject to the constraint x − y =...
