Answer:
a. $180,000 Favorable
b. $189,000 Unfavorable
c. Lowering the training facility price didn't raise sales.
Explanation:
a. Sales Volume Variance = (Actual hours - Budgeted hours) × Budgeted Revenue per hour
Sales Volume Variance = (31,500 - 30,000) × $120
= 1,500 × $120
= $180,000 Favorable
b. Flexible Budget Variance = (Actual revenue per hour - Budgeted revenue per hour) × Actual hours of training
= ($114 - $120) × 31,500
= $189,000 Unfavorable
c. Lowering the training service price did not raise sales. Because, according to actual training hours, actual revenue is lower than budget revenue.
