ANSWER

B. 56

Step-by-step explanation

The average temperature is the sum of all the temperatures of the week divided by the number of days the temperature was taken:


65=(76+70+x+68+55)/(5)

Solving for x:


\begin{gathered} 65\cdot5=269+x \\ 325-269=x \\ x=56 \end{gathered}

The temperature on Wednesday was 56 ºF
