5. The Precision Writing Instruments Company makes two pen designs—the Cordova design and the Savannah design. These data apply, regardless of which of two pen designs is being implemented.

Materials cost per pen is $6.

Labor cost per pen is $5.

Production overhead is $1,000,000.

Advertising and promotion is $1,000,000.

Marketing research has estimated the following demand functions for the next year of sales for the two pen designs where Q represents demand in thousands and P represents price. For the Cordova design, Q = 150 - 2.5P. For the Savannah design, Q = 175 - 2.1P. What are the total costs for sales of 500,000 units of the Cordova design?
