Unit 1 WebQuest - Internet Project

 Vacation Travelers Include More Kids

In addition, you must include the cost of transportation, lodging, and entertainment in a one—page report to the head of the travel agency for each of the three packages. This information will not be part of the brochure or Web page designed for the families.
1. Will the cost of each vacation be the same at all times of the year?
2. What factors might affect the cost of the vacation package?
3. What type of graph would be best for showing the temperature variations for the travel destination?
4. Would the Internet be a useful tool in estimating the cost of meals, since meals are not included in the plan?
5. How could you use a spreadsheet to find the cost of different vacation packages?

A student collected these data about the average high and low temperatures for Orlando, Florida, using the Internet.

1. Let numbers represent the months. For example, let 1 be January, 2 be February, and so on. Write two sets of ordered pairs. The first set will be (month, high temperature) and the second set will be (month, low temperature).
2. Construct a scatter plot of the data. Let the horizontal axis represent months and the vertical axis represent temperatures. Plot the first set of ordered pairs with a red colored pencil. Plot the second set of ordered pairs with a blue colored pencil.
3. Describe the two scatter plots.
4. Why would travelers be interested in your scatter plot?

Lesson 2—4
A popular amusement park offers a discount if you buy 4 tickets or more. The regular price of the tickets is \$50 and the discount is \$5 per ticket when buying 4 or more.

1. Show how you can use integers to find the total cost of 4 tickets with the discount.
2. Write an algebraic expression to show the cost of any number of tickets t using the discount. Assume that the number of tickets is always 4 or more.

Lesson 3—7
For a particular vacation, the cost of each round—trip airline ticket is \$275.00, the cost of each night's lodging is \$99.00, and the cost of amusement park tickets for each person for the entire seven days is \$254.00.

1. What is the cost of this vacation for four people for seven days? (The cost of the night's lodging is one room for the four people to share.)
2. Suppose that the cost of airline tickets can vary and the cost of the amusement park tickets can also vary, but the room charge stays constant at \$99.00. Let a = the cost of each airline ticket and let p = the cost of each amusement park ticket. Write a formula for calculating the cost of this vacation for four people for seven days.
3. How could you use a formula, like the one you wrote in part b, to help you complete this WebQuest?
