The flexible budget performance report should be prepared using only a single cost driver (Option A).
A management report called a flexible budget performance report contrasts the period's actual revenues and costs with those projected based on the actual sales volume.
With a flexible budget estimate, non-fixed costs are modified according to variables like sales volume or the quantity of products you produce. The flexible budget takes that into account if your increased product output has increased raw material expenses. The deviations that this algorithm cannot account for are highlighted in the performance report.
