stion 9 (30 points) Delta Company reported a $3000 unfavorable spending (price) variance for variable overhead and a $6000 unfavorable budget variance for fixed overhead. The manufacturing overheads are allocated based on machine hours. The standard rate of machine hours per unit production is estimated to be 2.5 hours. Delta planned to produce 6,000 units, the corresponding budget variable overhead is $45,000. Delta actually produced 4,000 units. A total of 9,000 machine hours were worked. Total actual overhead was $58,000. Estimated number of hours for computing the fixed-overhead application rate was 11,000. Required: answer the following problems. You must provide steps, logic, rationale, etc. to support your answer. Final numbers and/or conclusions do NOT warrant the majority of the points for the following problems. 1. Find (a) variable overhead efficiency variance, and indicate whether it is favorable or unfavorable and (b) actual VOH cost. Hint for (a): calculate "SP" using budget VOH cost, standard rate of MH per unit, and planned production units. Then, be careful about how you calculate "S" 2. Find fixed-overhead volume variance. Indicate whether it is favorable or unfavorable. C - Paragraph A &
