Dr. Gulakowicz is an orthodontist. She estimates that adding two new chairs will increase fixed costs by $149,000, including the annual equivalent cost of the capital investment and the salary of one more technician. Each new patient is expected to bring in $3,040 per year in additional revenue, with variable costs estimated at $1,030 per patient. The two new chairs will allow Dr. Gulakowicz to expand her practice by as many as 205 patients annually. How many patients would have to be added for the new process to break even?

Scenario C: Suppose you are given the process flowchart shown below. There are no buffers between tasks. Task 1 and 2 produce "Part A", and Task 3 and 4 produce "Part B"; Task 5 assembles each unit of a finished product by combining one unit of "Part A" with one unit of "Part B". Using this, answer the next 3 questions: Tpt Cap. = 10 units/hour- Tpt Cap. = 15 units/hour Task 1 5 ● 8 10 15 20 Task 3 Tpt Cap. = 5 units/hour Task 2 Tpt Cap. = 8 units/hour Task 4 Tpt Cap. = 20 units/hour Task 5 In this scenario, how many units would Task 5 actually produce each hour?
