Determine the profit with 10% of increase in enrolment and percentage of profitability.
c.
Explanation of Solution
Given information:
Number of students are 22. The salary of instructor is $6,000 per course taught. The F services offer course of instruction $700 per student to the employees of N incorporation

Excel workings:
Percentage change in profits:
Hence, the percentage change in profitability is 17.5%.
Percentage change in revenue:
Hence, the percentage change in profitability is 10%.
d.
Determine the profit with 10% of decrease in enrolment and percentage of profitability.
d.
Explanation of Solution
Given information:
Number of students are 18. The salary of instructor is $6,000 per course taught. The F services offer course of instruction at $700 per student to the employees of N incorporation
Excel spreadsheet:
Excel workings:
Percentage change in revenue and profitability:
Hence, the percentage change in profitability is 17.5%.
Hence, the percentage change in profitability is 10%.
e.
The reason for 10% shift in enrollment produces more than 10% shift in profitability and the term identifies this phenomenon.
e.
Explanation of Solution
The term which identifies these phenomena is operating leverage. This causes the percentage change in profitability to higher than the percentage change in revenue.
This is because that the fixed cost remains same and covered and there is no variable cost. So each additional dollar of revenue pays directly to the profitability.
2)f.
Whether the cost of instruction is fixed or variable cost
2)f.
Explanation of Solution
Given information:
The instructor needs $300 per person attending the class. The F services offer course of instruction at $700 per student to the employees of N incorporation

Hence, the percentage change in revenue is 10%.
i.
Determine the profit with 10% of decrease in enrolment and percentage of profitability.
i.
Explanation of Solution
Given information:
Number of students are 18. The instructor needs $300 per person attending the class. The F services offer course of instruction at $700 per student to the employees of N incorporation
Excel spreadsheet:
Percentage change in revenue and profit:
Hence, the percentage change in profitability is 10%.
Hence, the percentage change in revenue is 10%.
j.
The reason for 10% shift in enrollment produces relative 10% shift in profitability.

l.
Whether the cost of work book is fixed or variable cost
l.

- Problem 2-19A (Algo) Context-sensitive nature of cost behavior classifications LO 2-1 Vernon Bank's start-up division establishes new branch banks. Each branch opens with three tellers. Total teller cost per branch is $96,000 per year. The three tellers combined can process up to 85,000 customer transactions per year. If a branch does not attain a volume of at least 55,000 transactions during its first year of operations, it is closed. If the demand for services exceeds 85,00O transactions, an additional teller is hired and the branch is transferred from the start-up division to regular operations. Required a. What is the relevant range of activity for new branch banks? b. Determine the amount of teller cost in total and the average teller cost per transaction for a branch that processes 55,000, 65,000, 75,000, or 85,000 transactions. In this case (the activity base is the number of transactions for a specific branch), is the teller cost a fixed or a variable cost? c.
