The company's controller gathered additional information on fixed costs to see why they were so high. The following information on activities and drivers was gathered: In addition, Model 1 requires the rental of specialized equipment costing $22,000 per year. Required: 1. Reformulate the segmented income statement using the additional information on activities. Use a minus sign to indicate any negative margins. Do NOT round interim calculations and, if required, round your answer to the nearest dollar. If amount box does not require an entry, leave it blank or enter "0". 2. Using your answer to Requirement 1 , assume that Reshier Company is considering dropping any model with a negative product margin. What are the alternatives? Which alternative is more cost effective and by how much? (Assume that any traceable fixed costs can be avoided.) Do NOT round interim calculations and, if required, round your answer to the nearest dollar. will add \$ to operating income 3. What if Reshier Company can only avoid 184 hours of engineering time and 5,250 hours of setup time that are attributable to Model 1 ? How does that affect the alternatives presented in Requirement 2? Which alternative is more cost effective and by how much? Do NOT round interim calculations and, if required, round your answer to the nearest dollar. will add $ X to operating income
