24. Congratulations! You have just won a jet ski worth $8000. The depreciated value of the jet ski

(V) after t years is given by V=8000−725t, 0 ≤ t ≤ 11.

a. Use a graphing utility to graph the equation. Include a t-chart with at least 5 key points with your

accurate labeled graph.

b. After how many years will the jet ski be worth $5100? Show all of your work or explain how you

came up with your answer.

c. What will be the value of the jet ski after 9 years? Show all of your work or explain how you

came up with your answer.

25. The cost of installing insulation in a particular two-bedroom house is $1080. Present monthly

heating bills average $60, but the insulation is expected to reduce the heating cost by 10%. How

many months will it take to recover the cost of the insulation? Show all of your work or explain

how you came up with your solution.
