the histogram below represents the high temperatures recorded each day over a one month period.

7 days=80-82 degrees Celsius, 9 days=82-84 degrees Celsius, 6 days=84-86 degrees Celsius, 5 days=86-88 degrees Celsius, and 3 days=88-90 degrees Celsius.

How many days had a temperature of below 86?

Assuming that the histogram is represented by the given numbers:

7 days = 80 to 82 degrees Celsius

9 days = 82 to 84 degrees Celsius

6 days = 84 to 86 degrees Celsius

5 days = 86 to 88 degrees Celsius

3 days = 88 to 90 degrees Celsius

The days with a temperature below 86 degrees Celsius are day 7, 9, and 6.
