Question

Suppose the average temperature for a 4-day period in Chicago, Illinois, is -8°C. After the next day, the 5-day average is -9°C. What was the low temperature for the fifth day?

Answer 1

The low temperature for the fifth day is -13°C.

Step-by-step explanation:

To find the low temperature for the fifth day, we can use the average temperature formula. Since the average temperature for the 4-day period is -8°C and the 5-day average is -9°C, the total temperature for the five days is -9°C * 5 = -45°C. The sum of the temperatures for the first four days is -8°C * 4 = -32°C. Therefore, the low temperature for the fifth day is -45°C - (-32°C) = -45°C + 32°C = -13°C.
