Answer:
Please find the detailed answer as follows:
Explanation:
a) Predetermined overhead rate = Estimated manufacturing overhead cost   / Estimated total units in the allocation based
Predetermined overhead rate = 600,000 / 500,000 = 1.2 perunit
b) Total fixed cost spending variance = Actual fixed overhead cost - Estimated overhead cost
                                                          = 599,400 - 600,000
                                                          = 600 (F) Favourable
c) Total fixed cost volume variance = Actual fixed overheads - Estimated fixed overheads
   Actual fixed overheads = Estimated fixed overhead rate * Actual units produced
                                         = 1.2 * 508,000 = $609,600
Total fixed cost volume variance =$ 609,600 - $600,000 = $9600 (F) Favourable
 
        
             
        
        
        
The two correct options are:
