The Hardware Department of HD&L Products shows net sale of $3,500,000 cost of goods sold of $1,780,000 and operating expenses of $1,400,000. The Paint Department has net sales of $4,720,000 cost of goods sold of $3,100,750 and operating expenses of $149,000.

What is the operating expense percentage for the hardware department?

What is the operating income for the paint department?

I think I got the operating expense percentage : 40% ( I hope that is right..) I can't figure out the operating income - i believe it is gross income / net sales. but... where do I get the gross income?

My brain is fried - save me.
