I need the answers for questions 1 to 5 step by step

thank you

Assume you can produce 20 units per hour. Each operator (of each step A, B, and C) receives regular wages of $12 hhour for the first 8 hours, and overtime wages of $15/ hour for any additional time. Ten hours per day is the maximum work time permitted. A finished unit sells for $15 while its direct material cost is $5 per unit. What is the profit during the regular 8 hours? Answer: What is the profit during including overtime? Answer: Would you hire a skilled operator whose wage rate was $20 /hour (regular time), but could perform step B at a processing time of 2 minutes/unit? (Assume no overtime is used.) What is the new process capacity in units per hour with the new skilled operator for process step B? What is the result of the profit with the skilled operator minus the profit without the new skilled operator
