Answer:
13,000 units.
Explanation:
High-Low level method formula:
Variable Cost per unit = (Y2 - Y1) ÷ (X2 - X1)
y2 is the total cost at highest level of activity;
y1 is the total cost at lowest level of activity;
x2 are the number of units/labor hours etc. at highest level of activity; and
x1 are the number of units/labor hours etc. at lowest level of activity
= ($20,900 - $15,500) ÷ (1900 - 1100
)
= $6.75 per unit.
Mark’s monthly Salary = Total Compensation – Sales commission
= $20,900 - 1900 × $6.75
= $8,075
Calculation of the total number of units sold in a year when Mark's total compensation amounted to $184,650:
Sales Commission earned by Mark:
= Total Compensation - Mark’s yearly Salary
= $184,650 - ($8,075 × 12)
= $87,750
Calculation of total number of units sold in a year:
= Sales Commission earned during the year ÷ Sales Commission per unit
= 87,750 ÷ $6.75
= 13,000 units.
