Lopez Corporation has collected the following information after its first year of sales. Net sales were $1,600,000 on 100,000 units; selling expenses $240,000 (40% variable and 60% fixed); direct materials $511,000; direct labor $285,000; administrative expenses $280,000 (20% variable and 80% fixed); manufacturing overhead $360,000 (70% variable and 30%). Top management has asked you to do a CVP analysis so that it can make plans for the coming year. It has projected that unit sales will increase by 10% next year. Instructions The company is considering a purchase of equipment that would reduce its direct labor costs by $104,000 and would change its manufacturing overhead costs to 30% variable and 70% fixed (assume total manufacturing overhead costs is $360,000, as above). It is also considering switching to a pure commission basis for its sales staff. This would change selling expenses to 90% variable and 10% fixed (assume total selling expense is $240,000, as above). Assuming that net sales remain at first-year levels, compute (1) the contribution margin and (2) the contribution margin ratio, and recomputed (3) the break-even point in sales dollars.
