I am struggling on part 4a-c , if you could show work it would be much appreciated !

Morton Company's budgeted variable manufacturing overhead is $2.50 per direct labor-hour and its budgeted fixed manufacturing overhead is $180,000 per year. The company manufactures a single product whose standard direct labor-hours per unit is 2.5 hours. The standard direct labor wage rate is $10 per hour. The standards also allow 3 feet of raw material per unit at a standard cost of $7 per foot. Although normal activity is 60,000 direct labor-hours each year, the company expects to operate at a 50,000-hour level of activity this year. Required: 1. Assume that the company chooses 50,000 direct labor-hours as the denominator level of activity, Compute the predetermined overhead rate, breaking it down into variable and fixed cost elements. 2. Assume that the company chooses 60,000 direct labor-hours as the denominator level of activity. Compute the predetermined overhead rate, breaking it down into variable and fixed cost elements. 3. Complete two standard cost cards for 50,000 & 60,000 DLHS. 4. Assume that the company actually produces 21,200 units and works 54,000 direct labor-hours during the year. Actual manufacturing overhead costs for the year are: Variable manufacturing overhead cost Pixed manufacturing overhead cost Total manufacturing overhead cost $ 136,000 181,500 $ 317,500 a. Compute the standard direct labor-hours allowed for this year's production. b. Complete the Manufacturing Overhead T-account below. Assume that the company uses 50,000 direct labor-hours (normal activity) as the denominator activity figure in computing predetermined overhead rates, as you have done in (1) above. c. Assume that the company uses 50,000 direct labor-hours (normal activity) as the denominator activity figure in computing predetermined overhead rates, as you have done in requirement (1)
