The problem asks us to find by how many degrees Fahrenheit the temperature increased, given that the lowest temperature was $-8^\circ F$ and the highest was $24^\circ F$.

Solution:

The temperature increase is calculated by finding the difference between the highest and lowest temperatures:

$\text{Increase} = \text{Final temperature} - \text{Initial temperature}$ $\text{Increase} = 24^\circ F - (-8^\circ F) = 24^\circ F + 8^\circ F = 32^\circ F$

Thus, the temperature increased by $32^\circ F$.

The correct answer is E. 32°.
