I asked this question and the calculations were WRONG I can not figure this out to get the correct answers please provide correct steps so I can learn how to properly calculate I included screen shots of the calculations provided to me 
Single Plantwide Factory Overhead Rate Scrumptious Snacks Inc. manufactures three types of snack foods: tortilla chips, potato chips, and pretzels. The company has budgeted the following costs for the upcoming period: Factory overhead is allocated to the three products on the basis of processing hours. The products had the following production budget and processing hours per case: If required, round all per-case answers to the nearest cent. a. Determine the single plantwide factory overhead rate. X per processing hour b. Use the overhead rate in (a) to determine the amount of total and per-case overhead allocated to each of the three products under generally accepted accounting principles. a. Total processing hours = (Tortilla chips cases Processing hours per case) + (Potato chips cases Processing hours per case) + (Pretzels cases Processing hours per case) =(2,7000.10)+(2,1000.12)+(6,6000.15)=1,512 Single plantwide factory overhead rate = Budgeted costs / Total processing hours =1,512$113,400=$75 Single plantwide overhead rate =$75 per processing hour b. Calculation for Allocation of factory overhead Total factory overhead for Tortilla chips = Single plantwide overhead rate Budgeted volume for Tortilla chips Processing hours per case =$752,7000.10=$20,250.00 Total factory overhead for Potato chips = Single plantwide overhead rate * Budgeted volume for Potato chips * Processing hours per case =$752,1000.12=$18,900.00 Total factory overhead for Pretzels = Single plantwide overhead rate Budgeted volume for Pretzels Processing hours per case =$756,6000.15=$74,250.00 Per - case factory overhead for Tortilla chips = Total factory overhead for Tortilla chips / Budgeted volume =270$20,250=$7.50 Per case factory overhead for Potato chips = Total factory overhead for Potato chips / Budgeted volume for Potato chips =2,100$18,900=$9 Per case factory overhead for Pretzels = Total factory overhead for Pretzels / Budgeted volume for Pretzels =6,600$74,250=$11.25 a. Single plantwide overhead rate =$75 per processing hour b
