Answer:
a.$52,816
Explanation:
Calculation to determine total fixed costs
First step
Variable cost per unit = (Highest activity cost - Lowest activity cost)/(Highest activity - Lowest activity)
Variable cost per unit= ( 82,800-64,900)/(3,200-1,290)
Variable cost per unit= 17,900/1910
Variable cost per unit= $9.37 per unit
Now let determine the Fixed cost
Fixed cost = Highest activity cost - Highest activity x Variable cost per hour
Fixed cost= $82,800 - 3,200 x 9.37
Fixed cost= $82,800-$29,984
Fixed cost= $52,816
Therefore Using the high-low method of cost estimation, total fixed costs are $52,816
