X and Y are factors of production. X's marginal product is 30 and Y's marginal product is 20. X=5 dollars for each unit, Y= 4 dollars for each unit. Since Y costs less than X, can the firm keep produce the same output at a  cheaper cost by using less of X and more of Y? Explain why or why not.

Suppose that the Acme Gumball Company has a fixed proportions production function that requires it to use two gumball presses and one worker to produce 1,000 gumballs per hour. a. Explain why the cost per hour of producing 1,000 gumballs is 2v + w (where v is the hourly rent for gumball presses and w is the hourly wage). b. Assume Acme can produce any number of gumballs they want using this technology. Explain why the cost function in this case would be TC = q(2v +w), where q is output of gumballs per hour, measured in thousands of gumballs. c. What is the average and marginal cost of gumball production (again, measure output in thousands of gumballs)? (show the complete formula) Draw the graph for the average and marginal cost curves for gumballs assuming v=3, w-5 (show working) Now draw the graph for these curves for  v=6, w=5.( show working) Explain why these curves have shifted.

True/False: Ryan has coffee shop. If the marginal cost of producing the tenth cup of coffee is $1.50, and if the average total cost of producing the nine cups of coffee is $2, then find the average total cost of producing the ten cups of coffee. Show your work.

Joanne sells silk screened T-shirts at community festivals and craft fairs. Her marginal cost to produce one T-shirt is $3.50. Her total cost to produce 70 T-shirts is $305, and she sells them for $7 each a. Find the linear cost function for Joanne's T-shirt production b. How many T-shirts must she produce and sell in order to break even? c. How many T-shirts must she produce and sell to make a profit of $700? a. The linear cost function is C(x)= b. Joanne must produce and sell c. Joanine must produce and sell T-shirts in order to break even, because the number of T-shirts must be a whole number T-shirts to make a profit of $700, because the number of T-shirts must be a whole number

fixed cost is the same at each output level except when no output is produced. when a firm produces no output,there are no fix cost. true or false? explain

explain why the lower marginal cost firm can never produce the same as the high marginal cost firm
