Questions
A student collected these data about the average high and
low temperatures for Orlando, Florida, using the Internet.
- 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).
- 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.
- Describe the two scatter plots.
- Why would travelers be interested
in your scatter plot?
Lesson 24
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.
- Show how you can use integers
to find the total cost of 4 tickets with the discount.
- 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 37
For a particular vacation, the cost of each roundtrip
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.
- 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.)
- 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.
- How could you use a formula, like
the one you wrote in part b, to help you complete this WebQuest?
