I'd just like my work checked on this problem, please and thank you.

Selling price per unit Variable costs per unit Product G $140 Product B $170 102 Contribution margin per unit $ 85 $ 68 Machine hours to produce 1 unit Maximum unit sales per month 0.4 hours 500 units 1.0 hours 200 units The company presently operates the machine for a single eight-hour shift for 22 working days each month Management is thinking about operating the machine for two shifts, which will increase its productivity by another eight hours per day for 22 days per month. This change would require $8,500 additional fixed costs per month. (Round hours per unit answers to 1 decimal place. Enter operating losses, if any, as negative values.) 1. Determine the contribution margin per machine hour that each product generates Product G Product EB Contribution margin per unit Variable costs Contribution margin per mach 140.00 $ 55.0 212.50 $ 170.00 ine hour 68.00 Product G Product B Total Maximum number of units to be sold 500 200 Hours required to produce maximum units 200 200 400 2. How many units of Product G and Product B should the company produce if it continues to operate with only one shift? How much total contribution margin does this mix produce each month?
