1 answer

To find the temperature at midnight, we need to subtract the decrease in temperature from the noon temperature.

  1. Noon temperature = \( 11.4^\circ F \)
  2. Decrease in temperature = \( 15.7^\circ F \)

Now, we calculate the midnight temperature:

\[ \text{Midnight temperature} = \text{Noon temperature} - \text{Decrease} \]

\[ \text{Midnight temperature} = 11.4^\circ F - 15.7^\circ F \]

Now performing the subtraction:

\[ 11.4 - 15.7 = -4.3^\circ F \]

So, the temperature at midnight is \( -4.3^\circ F \).

The correct answer is:

A -4.3°F
