The cost effects of growth component are:
Direct materials costs (315,000 − 300,000) $8 = $120,000 U
Manufacturing conversion costs (250 − 250) $8,000 = 0
Selling & customer-service costs (100 − 100) $25,000 = 0
Cost effect of growth $120,000 U

Direct materials costs ($8.50 − $8) 315,000 = $157,500 U
Manufacturing conversion costs ($8,100 − $8,000) 250 = 25,000 U
Selling & customer-service costs ($9,900 − $10,000) 100 = 10,000 F
Cost effect of price-recovery $172,500 U
In summary, the net increase in operating income as a result of the price-recovery component equals:
Revenue effect of price-recovery $420,000 F
Cost effect of price-recovery 172,500 U
Change in operating income due to price-recovery $247,500 F
