Casino Pest Control (CPC) provides services to residential households by an application of a special chemical mix that varies somewhat in proportion based on environmental factors. CPC mixes two chemicals, Red-10 and Blue-12, in proportions depending on the climate and the particular pest problems of the neighborhood. A standard mix calls for a tank of the mixture to combine 60 percent Red-10 and 40 percent Blue-12. That is, a quart of the standard mixture contains 0.6 quarts of Red-10 and 0.4 quarts of Blue-12. Red-10 has a standard cost of $7 per quart and Blue-12 has a standard cost of $17.50 per quart. Each quart can treat 100 square yards. CPC expected to treat 500,000 square yards in May. CPC actually treated 510,000 square yards in May. The company used 2,920 quarts of Red-10 and 2,120 quarts of Blue-12. The actual total cost of Red-10 purchased in May was \$22,192 and \$34,980 for the Blue-12. CPC does not hold any materials inventory. Required: a.
