Answer:
25.3°F
Explanation:
We need to find the difference between the temperature on August 27, 1975, and the average temperature. So, the difference is equal to:
107 °F - 81.7°F = 25.3°F
It means that on August 27, 1975, the temperature was 25.3°F hotter than average.
So... if we take 22.8 to be the 100%, then it dropped to 12.1,
the difference in between being 22.8 - 12.1 or 10.7 decrease
so... what is 10.7 in percentage, of 22.8?
well

solve for "x"
