### Traffic Patterns and Analysis

The graph illustrates the relationship between the number of cars on a specific road and the time of day, specifically between 5:00 A.M. and 9:00 A.M. Please complete parts (a) through (e) below.

#### Traffic Pattern Graph

- **Axes**: 
  - The x-axis represents the time of day, marked at regular intervals from 5 A.M. to 9 A.M.
  - The y-axis indicates the number of cars, ranging from 300 to 900.
  
- **Plot Description**:
  - The graph's line starts at approximately 300 cars at 5 A.M.
  - There is a gradual increase in the number of cars until 6:30 A.M.
  - A sharper increase occurs from 6:30 A.M. to 7:30 A.M., where the number of cars reaches around 700.
  - From 7:30 A.M. to 8 A.M., the number of cars peaks at about 750.
  - After 8 A.M., there is a decline leading to 9 A.M., where the number decreases to around 600.

#### Problem to Solve:

**a.** What was the increase in the number of cars on the road between 7:00 A.M. and 7:30 A.M.?

- **Answer Box**:
  - [ ] car(s)
  - (Type a whole number.) 

This exercise helps students interpret and analyze data from a line graph concerning traffic patterns over a specified period.
