Answer:
The answer is b. manager's overall performance is 20% above expectations.
Explanation:
The budget overall performance is: Budgeted Contribution margin - Budgeted Controllable fixed costs = 1,000,000 - 500,000 = $500,000;
The Actual overall performance is: Actual Contribution margin - Actual Controllable fixed costs = 1,050,000 - 450,000 = $600,000;
Variance in dollar term of actual overall performance over budget overall performance = $600,000 - $500,000 = $100,000
% variance of actual overall performance over budget overall performance = 100,000/500,000 = 20%
Thus, actual overall performance is 20% above expectation.
