Answer:
The correct answer is d. $0.31 per client-visit; $24,766 per month.
Explanation:
The costs can be of fixed nature or a variable nature or of a mixed nature. A mixed costs contains a component of both fixed and variable costs. The high-low method is used to calculate the variable component per unit of a mixed cost. Th formula for high low method is:
Variable cost per unit = (Highest activity cost - Lowest activity cost) / (Highest activity level - Lowest activity level)
the highest activity is in June, 13400 client visits and the highest cost is also of this activity. The lowest activity is in August, 11207 client visits and the lowest cost belongs to this activity.
Variable cost per unit = (28920 - 28235) / (13400 - 11207)
Variable cost per unit = $0.31 rounded off to two decimal places
The fixed cost = Total cost - total variable cost
Taking 13400 activity,
The fixed component is = 28920 - (0.31 * 13400) = $24766 per month
Thus, the correct answer is d.
