Brand Z's annual sales are affected by the sales of related products X and Y as follows: Each $1 million increase in sales of Brand X causes a $2.5 million decline in sales of Brand Z, whereas each $1 million increase in sales of Brand Y results in an increase of $0.4 million in sales of Brand Z. Currently, Brands X, Y, and Z are each selling $6 million per year. Model the sales of Brand Z using a linear function. (Let z = annual sales of Z (in millions of dollars), x = annual sales of X (in millions of dollars), and y= annual sales of Y (in millions of dollars).) Z= Need Help? Read It Watch It

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.

A baseball team plays in a stadium that holds 66000 spectators. With the ticket price at $12 the average attendence has been 29000. VWhen the price dropped to $10, the average attendence rose to 33000. Assume that attendence is linearly related to ticket price. What ticket price would maximize revenue? $ Submit Question
