    Finite Mathematics for the Managerial, Life, and Social Sciences, 12th edition, written by Soo T. Tan and published by Cengage Learning, helps your students see the relevance of mathematics in their lives. Praised by users for its clarity, easy-to-follow writing style, and excellent applications, the texts’ pedagogical features and exciting array of supplements equip students with the tools they need to make the most of their study time and succeed in the course. Emphasis is placed on helping students formulate, solve, and interpret results of applied problems. Graphs and illustrations are used to help students visualize the concepts being presented. The WebAssign component for this title includes student resources such as eBook links, Master It tutorials, Watch Its, Talk to a Tutor assistance, and a Personal Study Plan, as well as instructor resources.

    Question 1 demonstrates WebAssign's ability to accept any equivalent form of the equation of the line when appropriate.

    Question 2 lets a student enter coordinate points in a natural (x, y) form.

    Question 3 includes a Master It tutorial.

    Question 4 includes a Watch It video.

    Question 5 contains intermediate steps so that the student must answer more than a multiple choice question.

    Question 6 features grading for an expression with variables, where any equivalent form of the expression is accepted.

    Question 7 uses special grading for roster notation and prompts the student to use the appropriate forms in the answer box.

    Question 8 gives the student the opportunity to fill in a table with their calculated values.

    Question 9 illustrates matrix grading where the entire matrix is graded as a single response rather than each element individually. This demo assignment allows many submissions and allows you to try another version of the same question for practice wherever the problem has randomized values.

Assignment Submission

For this assignment, you submit answers by question parts. The number of submissions remaining for each question part only changes if you submit or change the answer.

Paula is considering the purchase of a new car. She has narrowed her search to two cars that are equally appealing to her. Car A costs $28,000, and Car B costs $28,300. The manufacturer of Car A is offering 0% financing for 48 months with zero down, while the manufacturer of Car B is offering a rebate of $2000 at the time of purchase plus financing at the rate of 3%/year compounded monthly over 48 months with zero down. If Paula has decided to buy the car with the lower net cost to her, which car should she purchase? (Round numerical values to the nearest cent.)
net cost of Car A     $
net cost of Car B     $
car she should purchase
