Answer:
A. $50 per unit
B. $900,000
Explanation:
(a) Computation for the variable cost per unit using this formula
Variable cost per unit=(Total cost at highest level-Total cost at lowest level)/(Highest level-Lowest level)
Let plug in the formula
Variable cost per unit=(2,400,000-1,900,000)/(30,000-20,000)
Variable cost per unit=500,000/10,000
Variable cost per unit=$50 per unit
Therefore The Variable cost per unit will be $50 per unit
B. Computation to determine the Total fixed cost
Total fixed cost=2,400,0000-(50*30,000)
Total fixed cost=2,400,0000-1,500,000
Total fixed cost=$900,000
Therefore The Total fixed cost will be $900,000
