Handheld fiber-optic meters with white light polarization interferometry are useful for measuring
temperature, pressure, and strain in electrically noisy environments. The fixed costs associated
with manufacturing are $800,000 per year. If a base unit sells for $2950 and its variable cost is
$2075,
(a ) how many units must be sold each year for breakeven?
(b ) what will the profit be for sales of 3000 units per year?
Handheld fiber optic meters with white light polarization interferometry are useful for measuring temperature, pressure, and strain in electrically noisy environments. The fixed costs associated with manufacturing are $800,000 per year. If variable costs are $290 per unit and the company sells 4000 units per year, at what selling price per unit will the company break even?
Since many U.S. Navy aircraft are at or near their usual retirement age of 30 years, military officials want a precise system to assess when aircraft should be taken out of service. A computational method developed at Carnegie Mellon maps in 3-D the microstructure of aircraft materials in their present state so that engineers can test them under different conditions of moisture, salt, dirt, etc. Military officials can then determine if an aircraft is fine, is in need of overhaul, or should be retired. If the 3-D system allows the Navy to use one airplane 2 years longer than it normally would have been used, thereby delaying the purchase of a $20 million aircraft for 2 years, what is the present worth of the assessment system at an interest rate of 8% per year?

- custom-designed home, FD, the prime contractor, realized he was not going to make the big profit that he had anticipated due to the many unique features of the home for which he had not correctly estimated the cost to the owners. The contract was fixed-price with no more than 10% override on the total cost. As time proceeded, FD took the choices of the owners on appliances, finishing work on the floors and walls, and many other features and purchased look-alike substitutes from questionable-quality, internationallybased manufacturers and vendors. After living in the house for only 3 years, the owners were so disappointed with the quality of work that they decided to bring a law suit against FD and his company for breach of contract. However, they needed sound reasons upon which to base their legal claims against FD, were the case to go to court. One of the owners, being an engineer, decided to consult the Code of Ethics for Engineers to gain insight into what may be substantial…arrow_forwardA corn refining company produces corn gluten cattle feed at a variable cost of $83 per ton.

- A small company heats its building and spends $8,800 per year on natural gas for this purpose. Cost increases of natural gas are expected to be 9% per year starting one year from now (i.e., the first cash flow is $9,592 at EOY one). Their maintenance on the gas furnace is $355 per year, and this expense is expected to increase by 12% per year starting one year from now (i.e. the first cash flow for this expense is $397.60 at the EOY one).
