Revenue It is now the end of July, and OHaganBooks.com’s e-commerce manager bursts into the CEO’s office. “I thought you might want to know, John, that our sales figures are exactly what I projected a month ago. Is that good market analysis or what?” OHaganBooks.com has charged an average of $5 for romance novels, $6 for science fiction novels, and $5.50 for horror novels. Use the projected July sales figures from above and matrix arithmetic to compute the total revenue OHaganBooks.com earned at each warehouse in July.
