Requirements

What is the budgeted sales price per unit?

What is the budgeted variable expense per unit?

What is the budgeted fixed cost for the period?

Compute the master budget variances. Be sure to indicate each variance as favorable $($F$)$ or unfavorable $($U$.)$

Management would like to determine the portion of the master budget variance that is $($a$)$ due to volume being different than originally anticipated and $($b$)$ due to some other unexpected cause. Prepare a flexible budget performance report to address these questions, using the actual sales volume of $53,500$ units and the budgeted sales volume of $50,000$ units. Use the original budget assumptions for sales price, variable cost per unit, and fixed costs, assuming the relevant range stretches from $45,000$ to $68,500$ units.

Using the flexible budget performance report you prepared for Requirement $5,$ answer the following questions:

a$.$ How much of the master budget variance $($calculated in Requirement $4)$ for operating income is due to volume being higher than expected?

b$.$ How much of the master budget variance for variable expenses is due to some cause other than volume?

c$.$ What could account for the flexible budget variance for sales revenue?

d$.$ What is the volume variance for foxed expenses? Why is it this amount?
