Question

Quizplus · Accepted Answer

To calculate CDD (Cooling Degree Days), we need to find the average of the highest and lowest temperatures for the day and subtract it from 65 degrees (the base temperature).

Average temperature = (77 + 61) / 2 = 69 degrees

CDD = 65 - 69 = -4

Since the CDD cannot be negative, we take the absolute value, which gives us 4. Therefore, the answer is choice C) 4.
