Practice questions
These are questions from previous years' exams and midterms. They do not reflect the questions I will ask, but should be suitable for practice.

.. question::
A small aerospace company is evaluating two alternatives: the purchase of an automatically fed machine or a manually fed machine. All projects in the company are expected to return at least 10% (before tax).
The auto-fed machine has an initial cost of $23,000, an estimated salvage value of $4000 and a predicted life of ten years. The expected production rate is 8 tons per hour, and the operating costs are $12 per hour. The annual maintenance cost is expected to be $3500.
The manually fed machine has a purchase price of $8000, 0 salvage value, a 5-year life and a production rate 6 tons per hour. The operating costs are $24 per hour, and the annual maintenance cost is $1500.
Some additional information:
#. Both machines produce product using the same feed material and energy, and they both produce products with the same value. #. There is no delay between ordering the machine and placing it in operation. #. We assume that the production (ton/year) will be the same every year #. The project has a ten-year life.
How many tons per year must be produced in order to justify the higher purchase cost of the auto-fed machine? You may analyze this problem using a before tax approach (without considering taxes or depreciation).
.. question::

.. question::

.. question::
Your company is establishing a new office in Calgary. You seem to be spending a lot of money. One of your co-workers says, “Don’t worry, we can depreciate the costs.”
1. Describe the key characteristics of costs that can be depreciated. 2. Explain how you determine the rate with which a specific cost is depreciated.
.. question::
Estimate the current Total Module cost to install a mixer-settler unit with six stages including interconnecting piping and pumps. The aqueous to oil ratio A:O is 1:1. The flow of aqueous feed to each unit is 9 L/s. All the units are to be rubber lined. The cost is to include nozzles and internals. The costs of tankage and crude removal are excluded.
