The graph represents the distribution of cities across different temperature intervals in July. The x-axis corresponds to temperature, while the y-axis indicates the number of cities.

To determine the number of cities with temperatures 70 degrees and above, we need to consider the intervals that start from or include the minimum value of 70 degrees on the x-axis. In this case, we have four intervals: 70-79, 80-89, 90-99, and 100-109.

By drawing horizontal lines from the top of each corresponding bar and extending them to i...
