Assignment: Cost Analysis and the Perfectly Competitive Market
In this assignment, you will define and calculate the remaining six major cost elements of a business when given the total costs and the quantity produced.
You will then use the computed costs to determine a minimum cost output level for that business.
Next, you will compute both the break-even price and the shutdown price for a hypothetical business in a perfectly competitive market.
Then you will determine if that business would incur an economic profit at various market prices, and if the business should continue to produce at each of those price levels.
Questions
Table 1 shows an LED light bulb manufacturer’s total cost of producing LED light bulbs at various output levels.

5. Brenda Smith operates her own farm raising chickens and producing eggs. She sells her eggs at the local farmers market, where there are several other egg producers also selling eggs by the dozen. (Brenda operates in a perfectly competitive market in which she is a “price taker.”) To make sure she does not lose money on selling eggs, she does an analysis of her costs for producing eggs as shown on Table 3.
