Problem of the Day The fine for a late movie at
a video store is 1.00 for the first day and
2.50 for each day after that. There is also a
1.00 fee if the movie is not rewound. What is
the total fine if the move is 4 days late and not
rewound?

4
Learn to interpret information given in a graph
or a table and make a graph to help solve
problems.

The table below show how quickly the temperature
can increase in a car that is left parked during
an afternoon of errands when the outside
temperature is 93?F.
6
Additional Example 1 Matching Situations to
Tables
The table gives the speeds in mi/h of three cars
at given times. Tell which car corresponds to the
situation.
7
Additional Example 1A Matching Situations to
Tables
A. Mr. Lee is traveling on the highway, and he
pulls over to make a call on his cell phone. Then
he gets back onto the highway.
Car 3 - Mr. Lee starts to slow down after 100.
After making his phone call, he gets back onto
the highway and resumes his speed of 55 mi/h.
8
Additional Example 1B Matching Situations to
Tables
B. Mrs. Healy is driving on the freeway between
100 and 120 and encounters no traffic.
Car 2 - Mrs. Healy car maintains a speed between
50 mi/h and 55 mi/h.
9
Additional Example 1C Matching Situations to
Tables
C. At 100 Mr. Johns estimates that he will
arrive at his destination in approximately 20
minutes.
Car 1 - Mr. Johns speed begins to decrease to 0
sometime between 115 and 120.

Try This Example 1A
The table gives the speed in mi/h of three
runners at the given times. Tell which runner
corresponds to the situation.

3 8 3 8 3 8
A. Jamie begins the race, and soon feels a pain
in a muscle. He is unable to complete the race.
Runner 2Jamie begins at a fast speed. His speed
decreases as he feels a pain in a muscle, and
then decreases to 0 when he stops.
11
Try This Example 1B
The table gives the speed in mi/h of three
runners at the given times. Tell which runner
corresponds to the situation.
Time 800 810 820 830
840 Runner 1 6 7 7 7 7 Runner 2 9 6 0 0 0 Runner
3 8 3 8 3 8
B. Melissa builds up her speed during the
beginning of the race. She maintains her running
speed for the remainder of the race.
Runner 1Melissa begins running at a rate of 6
mi/h and then speeds up to 7 mi/h. She maintains
7 mi/h for the remainder of the race.
12
Try This Example 1C
The table gives the speed in mi/h of three
runners at the given times. Tell which runner
corresponds to the situation.
Time 800 810 820 830
840 Runner 1 6 7 7 7 7 Runner 2 9 6 0 0 0 Runner
3 8 3 8 3 8
C. Ann decides to alternate between running and
walking during the race.
Runner 3Ann is running at a rate of 8 mi/h and
then walks at a rate of 3 mi/h. She continues
alternating between running and walking.

Graph 3
A. Jamie begins the race, and soon feels a pain
in a muscle. He is unable to complete the race.
Graph 2Jamie is unable to complete the race, so
his speed decreases to zero.

B. Melissa builds up her speed during the
beginning of the race. She maintains her running
speed for the remainder of the race.
Graph 1Melissas speed increases at the
beginning and then the graph remains constant.

Additional Example 3 Creating a Graph of a
Situation
Create a graph that illustrates the temperature
(?F) inside the car.

Try This Example 3
Create a graph that illustrates the information
in the table about the distance traveled during a
family vacation.

Lesson Quiz
Tell which table corresponds to the situation. A
tour bus sits at the gas station while the
mechanic inspects the tires. It then leaves and
make its first stop five miles down the road. The
bus then continues on to its destination by
getting on the expressway and driving 40 miles.
