Answer:
Variable Overhead Efficiency Variance = $24 Favorable
so correct option is c. $24 Favorable
Explanation:
given data
variable manufacturing overhead rate = $2.40 per machine hour
actual variable manufacturing overhead cost = $5,240
original budget = 2,100 machine hours
actual output = 2.280 machine hours
to find out
variable overhead efficiency variance
solution
we know Standard Cost Per Hour that is
Standard Time = 2100 hours
Standard Rate = $2.40 per hour
Standard Cost per unit = 2100 × $2.40 = $5040
and
Standard Cost for actual output will be
Standard Time = 2280 hours
Standard Rate = $2.40 per hour
Standard Cost per unit = 2280 × $2.40 = $5472
so actual overhead expenses will be
Actual Time = 2270 hours
Actual Rate = $2.31 per hour
Actual Cost = $5240
so
Variable Overhead Efficiency Variance will be
Variable Overhead Efficiency Variance = (Standard Hours - Actual Hours) × Standard Variable Overhead Rate ....................1
Variable Overhead Efficiency Variance = ( 2280 - 2270 ) × $2.40
Variable Overhead Efficiency Variance = $24 Favorable
so correct option is c. $24 Favorable
