Question

New Orleans averages 77% humidity in the mornings, but it decreases by 20% in the afternoon. What is the average relative humidity in the afternoon in New Orleans? (enter a percent rounded to the tenths place)

Answer 1

Answer: 61.6%

Step-by-step explanation:

The afternoon humidity average is 20% of the morning average.

The morning average is 77% so the afternoon average must be:

= Morning average * ( 1 - percentage decrease)

= 77% * (1 - 20%)

= 77% * 80%

= 61.6%
