Munoz, Inc., produces a special line of plastic toy racing cars. Munoz, Inc., produces the cars in batches. To manufacture a batch of the cars, Munoz, Inc., must set up the machines and molds. Setup costs are batch-level costs because they are associated with batches rather than individual units of products. A separate Setup Department is responsible for setting up machines and molds for different styles of car..Setup overhead costs consist of some costs that are variable and some costs that are fixed with respect to the number of setup-hours. The following information pertains to June 2016: Actual Static-budget
Amounts Amounts
Units produced and sold 15,000 11,250
Batch size (number of units per batch) 250 225
Setup-hours per batch 5 5.25
Variable overhead cost per setup-hour $40 $38
Total fixed setup overhead costs $12,000 $9,975
Required:
1) Calculate the efficiency variance for variable overhead setup costs.
2) Calculate the rate variance for variable overhead setup costs.
3) Calculate the flexible-budget spending variance for variable overhead setup costs.
4) Calculate the spending variance for fixed setup overhead costs.

Explanation:

1. Calculate the efficiency variance for variable overhead setup costs.

This will be calculated as:

= Standard Hours - Actual Hours) × Standard rate

= (15000/225 × 5.25 - 15000/250 × 5) × 38

= (350 - 300) × 38

= 50 × 38

= 1900 Favourable

2) Calculate the rate variance for variable overhead setup costs.

This will be:

= Standard rate- Actual rate) × Actual Hour

= (38-40) × (15000/250 × 5)

= -2 × 300

= -600 Unfavourable

3) Calculate the flexible-budget spending variance for variable overhead setup costs.

This will be the difference between the standard cost and the actual cost. This will be:

= (15000/225×5.25 ×38) - (15000/250×5 ×40)

= 13300 - 12000

= 1300 Favourable

4) Calculate the spending variance for fixed setup overhead costs.

what formular did you use.

This will be:

= Standard Cost - Actual Cost

= 9975-12000

= -2025 Unfavorable

answer; /// the above statement is (true);

a manufacturer of printed circuit boards uses exponential smoothing with trend to forecast monthly demand of its product. at the end of december, the company wishes to forecast sales for january. the estimate of trend through november has been 200 additional boards sold per month. average sales have been around 1000 units per month. the demand for december was 1100 units. the company uses α = 0.20 and β = 0.10. make a forecast including trend for the month of january.
