6-9 Consider the financial aspects of the digital thermometer project. The project cost is estimated at $10,000. The total manufacturing cost of the digital thermometer, as called for in the specifications, total $150 (that is, $95 parts plus $40 labor plus $15 overhead). In order to sell each digital thermometer, consider an additional cost of $50 to cover the company’s administrative overhead and selling expenses. The net selling price of each digital thermometer will be $250. Determine the following using general problem-solving skills without considering the changing value of money due to inflation:
• a. What is the net profit for each digital thermometer sold?
• b. If the net profit is used to pay off the project development costs, how many digital thermometers will have to be sold to recover the $10,000 investment?
• c. At the projected annual volume of 1000 units per year for the product, roughly how long will it take until the $10,000 is recovered? This is the break-even point for the company.
