Please let me know if my answers are correct. Thanks

Fixed costs = $8,000 Variable cost = $l0/unit Semi-variable cost = $5/unit + $900 Required Return = $1, 500 Tax rate = .40 Revenue = $20/unit Time = 100 hours Production units = 2,000 units Do 4 Break evens solving for number of units: shutdown point, at cost, at required return, at required return after tax. Fixed costs = $ 30/hr Variable cost = $16/hr *2, 500 Semi-variable cost = $14/hour + $500 Required Return = $3,000 Tax rate = .40 Revenue * $15/unit Production Units = 1,000 units Time period actual = 200 hours Do 4 Break - evens solving for number of hours: shutdown point, at cost, at required return, at return after tax
