Answer:
Answer:
1. Overhead over applied= $521,000
2. Factory Overhead   Dr.     $ 521,000
 Cost Of Goods Sold Cr.    $ 521,000
3. Work in Process,  (ratio)   $521,000 *    7%=  36,470
Finished Goods,              $521,000   *     19%=  98,990
 Cost of Goods Sold       $521,000    *    74%=  385,540
Total                        $521,000     100%
4. Difference between the two CGS= $ 136,060
Explanation:
Predetermined Overhead  Costs $1,152,000 
Estimated activity level of 72,000 machine-hours
Overhead rate= $ 1152,000/ 72,000= $ 16 per hour
Manufacturing overhead cost $551,000
Actual hours = 67,000 
 Overhead applied to WIP = 67,000 * 16= $ 1072,000
Overhead over applied= $ 1072,000 - $551000= $521,000
Part 2:
Factory Overhead   Dr.     $ 521,000
 Cost Of Goods Sold Cr.    $ 521,000
The Cost of Goods Sold is credited and Factory overhead is debited.
Part 3:
Suppose the overhead is applied in the following ratio
Work in Process,  (ratio)   $37,520          7%   (37520/536,00*100%)
Finished Goods,              $101,840         19%      (101840/536,00*100%)
 Cost of Goods Sold       $396, 640        74%     (396,640/536,00*100%)
Total                        $536,000     100%
The  overhead over applied  would be allocated in the following way applying the same ratio as determined above.
Work in Process,  (ratio)   $521,000 *    7%=  36,470
Finished Goods,              $521,000   *     19%=  98,990
 Cost of Goods Sold       $521,000    *    74%=  385,540
Total                        $521,000     100%
Part 4: 
Cost of Goods Sold ( overhead applied of $396, 640) $1,472,600
Less    Overhead   overapplied      $ 521,000
CGS = $ 951,000
Cost of Goods Sold (overhead applied to WIP & FG) $1,472,600
Less   Overapplied Overhead $ 385,540
CGS=  $ 1087,060
Difference between the two CGS = $ 1087,060- $ 951,000= $ 136,060
