For the first six months of the year, only 350 units had been sold at the established price, with variable costs as planned, and it was clear that the net profit after tax projection for 2022 would not be reached unless some actions were taken. Required (show your calculations): 1. If no changes are made, compute the number of units to sell to achieve its net profit 5 marks after tax for the year. 2.

Determine which alternative Duke should select to achieve its net profit after tax objective: a. Reduce the selling price by $40.

Total fixed costs and variable costs per unit will stay as budgeted. b. Lower variable cost per unit by $10 using less-expensive direct materials and slightly modified manufacturing techniques. The selling price will also be reduced by $30, and sales of 2 200 units are expected for the remainder of the year. C. Reduce fixed costs by $10 000 and lower the selling price by 5%. Variable cost per unit will be unchanged. Sales of 2000 units are expected for the remainder of the year
