P6-77B. Absorption and variable costing income statements (Learning Objective 6) Murphy's Foods produces frozen meals, which it sells for $7 each. The company uses the FIFO inventory costing method, and it computes a new monthly fixed manufacturing overhead rate based on the actual number of meals produced that month. All costs and production levels are exactly as planned. The following data are from the company's first two months in business: 1.

Prepare separate monthly income statements for January and for February, using (a) absorption costing and (b) variable costing. 3. Is operating income higher under absorption costing or variable costing in January? In February? Explain the pattern of differences in operating income based on absorption costing versus variable costing
