Can somebody please help me answer question b and c? Thank you

Nicole Limited is a company that produces machinery to customer orders, using a normal job-order cost system. It applies manufacturing overhead to production using a predetermined rate. This overhead rate is set at the beginning of each fiscal year by forecasting the years overhead and relating it to direct labour costs. The budget for 2016 was as follows: As at the end of the year, two jobs were incomplete. These were 1768B, with total direct labour charges of $110,000, and 1819C, with total direct labour charges of $390,000. On these jobs, machine hours were 287 hours for 1768B and 647 hours for 1819C. Direct materials issued for 1768B amounted to $220,000, and for 1819C they amounted to $420,000. Total charges to the Manufacturing Overhead Control account for the year were $897,000, and direct labour charges made to all jobs amounted to $1,583,600, representing 247,216 direct labour hours. There were no beginning inventories. In addition to the ending work in process just described, the ending finished goods inventory account showed a balance of $720,000. Sales for the year amounted to $6,201,355: cost of goods sold totalled $3,935,000: and sales, general, and administrative expenses were $1,857,870. The above amounts for inventories and the cost of goods sold have not been adjusted for any over- or under-application of manufacturing overhead to production. It is the company's practice to allocate any over- or under-applied overhead to inventories and the cost of goods sold. Instructions (a) Calculate the under- or over-applied manufacturing overhead for 2016. (b) Prorate the amount calculated in part (a) based on the ending balances (before prorating) of Work in Process, Finished Goods, and Cost of Goods Sold. (c) Prepare an income statement for the company for the year. The income tax rate is 40%
