Answer:
Step-by-step explanation:
a.) The cost of instruction is Variable cost relative to the number of students in a single course . As the instructors are paid on student basis @$700 per student in course
b.) Assuming the number of students are 20, Total Income is $700*20= $14,000
Total Expense is $6,000
Profit of $14,000-$6,000= $8,000
c.) Enrollment increases by 10% to 22 students
Total Income will rise to $700*22= $15,400
Profit of $15,400-$6,000= $9,400. It is $1,400 more than before.
d.) Enrollment decreases by 10% to 18 students
Total Income falls to $700*18= $12,600
Profit of $12,600-$6000= $6,200
