d) 6.5 degrees F

Answer 1

The temperature at the end of the evening is 8.5 degrees F.

Step-by-step explanation:

To find the temperature at the end of the evening, we need to calculate the total change in temperature throughout the day. The temperature at noon is 3.5 degrees F, and during the afternoon, it changes by 14.3 degrees F. In the evening, it changes by -9.3 degrees F. To find the temperature at the end of the evening, we add the changes in temperature to the initial temperature:

3.5 degrees F + 14.3 degrees F + (-9.3 degrees F) = 8.5 degrees F

Therefore, the temperature at the end of the evening is 8.5 degrees F.
