Total fixed costs are $2.9 million per year, variable production costs are $285 per unit, and the units are priced at $410 each. The equipment needed to begin production has an installed cost of $14.8 million. Because the implants are intended for professional singers, this equipment is considered industrial machinery and thus qualifies as seven-year MACRS property. In five years, this equipment can be sold for about 20 percent of its acquisition cost. The tax rate is 21 percent and the required return is 18 percent.

A system contains many processes. Three common processes that are “grouped” together are transaction corrections, adjustments, and cancellations. These three elements work to properly serve customers. Imagine a system that allows you to register for a class online. The online system must give you a way to correct any errors you made, such as registering for the wrong class. This would be a transaction correction. The system should also allow you to make adjustments, such as adding or dropping classes. Finally, the system should allow you to make cancellations, such as cancelling the registration process entirely. Notice that all three of these processes, correction, adjustment, and cancellation, work together to provide you with one service, which is registering for classes. What type of requirements are transaction corrections, adjustments, and cancellations? Select one. Question 4 options: A Functional Requirements B Nonfunctional Requirements
