Answer:
The total units produced are as follows:
January: 90000 units
February: 100000 units
March: 110000 units
Explanation:
The total units produced are as follows:
January: 90000 units
February: 100000 units
March: 110000 units
Wages for each month are calculated as:
January: Wages = (Units * Direct labor hours per unit) + (hours * wages per hour) = (90000*$0.75) + (22500*$15) = $405000
February: Wages = (Units * Direct labor hours per unit) + (hours * wages per hour) = (100000*$0.75) + (25000*$15) = $450000
March: Wages = (Units * Direct labor hours per unit) + (hours * wages per hour) = (110000*$0.75) + (27500*$15) = $495000
Utilities for each month is:
January: Utility: = (hours * Utility cost per direct labor hour) = 22500 * 1.20 = $27000
February: Utility: = (hours * Utility cost per direct labor hour) = 25000 * 1.20 = $30000
March: Utility: = (hours * Utility cost per direct labor hour) = 27500 * 1.20 = $33000
Since depreciation is fixed and do not flex it is the same for all the months at $60000
The total for each month is:
January: Total = Wages + Utilities + depreciation = $405000 + $27000 + $60000 = $492000
February: Total = Wages + Utilities + depreciation = $450000 + $30000 + $60000 = $540000
March: Total = Wages + Utilities + depreciation = $495000 + $33000 + $60000 = $588000
