Question 18 of 25 0.0/ 4.0 Points Use your knowledge of the process of "Writing an equation given two points" to solve the following problem: A vendor has learned that, by pricing his deep fried bananas on a stick at \$1.50 , sales will reach 110 per day. Raising the price to \$2.50 will cause the sales to fall to 70 per day. Let y be the number of the vendor sells at x dollars each. Write a linear equation that models the number of sold per day when the price is x dollars each. The linear equation is y = -40x+150 . Question 19 of 25 4.0/ 4.0 Points Choose the equation of the line that has a slope of - 3 and contains the point (2, 7). A. y = - 3x - 7 B. y = - 3x - 13 C. y = - 3x + 13 D. y = - 3x + 7 Question 20 of 25 4.0/ 4.0 Points Write the equation of the line with an undefined slope and containing the point (2, 3). A. x = 2 B. y = 0 C. x = 3 D. None of these. E. y = 3 Question 21 of 25 4.0/ 4.0 Points A truck rental company rents a moving truck one day by charging \$31 plus \$0.13 per mile. What is the cost of renting the truck if the truck is driven 140 miles? A. \$49.20 Feedback: Correct! Substitute and solve. B. \$12.80 C. None of these. D. \$32.82 E. \$434.00 Question 22 of 25 4.0/ 4.0 Points The linear model C = 800x + 20,000 represents the cost, in dollars, for a company to manufacture x items during a month. Based on this, how much does it cost to produce 800 items?

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
