Sanders Industries produced 1,500 Requirements tables last month. The standard 1. Calculate the variable variable manufacturing overhead overhead rate variance. (MOH) rate used by the company is 2. Calculate the variable $22 per machine hour. Each table overhead efficiency variance. requires 0.5 machine hours. Actual machine hours used last month were 770 , and the actual variable MOH rate last month was $23.50. Requirement 1. Calculate the variable overhead rate variance. Begin by determining the formula for the variable overhead rate variance, then compute the variable overhead rate variance. (Enter the variance as a positive number. Enter amounts in the formula to the nearest cent and then the final variance amount to the nearest whole dollar. Label the variance as favorable (F) or unfavorable (U).)
