An LP model for a marketing research application uses the variable HD to represent the number of homeowners interviewed during the day. The objective function minimizes the cost ofinterviewing this and other categories. There is a constraint that HD 2 160. The solution indicates that interviewing another homeowner during the day will increase costs by $5.00. Whatdoes this tell you about the HD variable?O The dual price for the HD constraint is -5.The objective function coefficient of HD is 5.The dual price for the HD constraint is 5.O The objective function coefficient of HD is -5.

Flying twice as farA flight from Los Angeles to ABQ is about 2 hours but is 670.2 miles.A flight from San Jose to Chicago is 4 hours but is 1859.0 miles.Can anyone explain why the travel time from San Jose to Chicago is notlonger and closer to 5.75 hours?If the distance increase by 2, shouldnt the time increase by a factorof 2 as well?1. Write a linear model for this question. Takeoff and landing will take a fixed amount of time. Actualtravel in the air will take time proportional to the distance traveled. Think about which of thevariables (time and distance) is the independent variable, and identify the slope and intercept withtheir units.2. Use the data in the quotation to estimate the two constants in your linear model.

Advertising You are the marketing director for a company that manufactures bodybuilding supplements and you are planning to run ads in Sports Illustrated and GQ Magazine. Based on readership data, you estimate that each one-page ad in Sports Illustrated will be read by 660,000 people in your target group, while each one-page ad in GQ will be read by 190,000. You would like your ads to be read by at least 3 million people in the target group and, to ensure the broadest possible audience, you would like to place at least two full-page ads in each magazine. Draw the feasible region that shows how many pages you can purchase in each magazine.
