Question

The average temperature for four days days was 22 degrees what must the temperature be on the fifth day in order to make 23 degrees the average temperature for the five days

Answer 1

27 degrees.

Explanation:

If the average is to be 23 degrees over 5 days then the total of the temperatures will be 5*23 = 115 degrees.

The total over the first 4 days = 22*4 = 88 degrees, so the temperature on the fifth day has to be 115 - 88 = 27 degrees.
