Anderson Inc. developed an annual budget at the start of the year, determining a budgeted
	variable-MOH cost of $230,400 and budgeted fixed-MOH cost of $556,800.
	Planned volume was 120,000 units and each unit required a standard cost driver of
	direct labour hours, where each unit should use a standard of 4 direct labour hours.
At the end of the year a total of 119,400 units were produced using 478,000 direct labour hours.
Actual variable overhead costs for the year were $230,600, and actual fixed overhead costs were $556,250.
(a) Calculate the budgeted variable-MOH rate per direct labour hour and standard variable-MOH cost per unit.
	Do the same for fixed-MOH.
(b) Determine the variable-MOH price and efficiency variances as of the end of the year and indicate if the
	variances are favourable or unfavourable.
(c) Determine the fixed-MOH price and volume variances as of the end of the year and indicate if the
	variances are favourable or unfavourable.
(d) Provide at least one plausible explanation for each variance.
