- A farmer finds there is a linear relationship between the number of bean stalks, n, she plants and the yield, y, each plant produces. When she plants 30 stalks, each plant yields 30 oz of beans. When she plants 34 stalks, each plant produces 28 oz of beans. Is the function from part (a) increasing or decreasing? How do you know?arrow_forwardA Webmaster has tracked an increasing number of registered users since the beginning of an advertising campaign. Before starting to advertise, he had 2,200 registered users and after 4 months of advertising he now has 5,480 registered users. Use this data to write a linear function that gives the total number of registered users, given the number of months after starting to advertise. Use the function to predict the number of registered users 8 months into the advertising campaign.arrow_forwardThe US Department of Health conducted a survey for the years 1985-2018 regarding the use of cigarettes. Datafrom those years indicate that the linear function y = −0.47x + 47.1 gives an estimate of the 18-25 age group using cigarettes. The variable x represents the number of years since 1985 and y represents the percentage of 18-25 year old individuals using cigarettes. Explain what the −0.47 represents in terms of time and the percentage of 18-25 year old individuals using cigarettes.arrow_forward
- A university is trying to determine what price to charge for tickets to football games. At a price of $20 per ticket, attendance averages 40,000 people per game.

What price per ticket should be charged in order to maximize revenue? How many people will attend at that price?arrow_forwardAbove are the graphs of the Cost, cc, of ordering nn wedding invitations from two different companies. a.
