Given data:
The initial value of the temperature is T= 31 degrees Fahrenheit.
The temperature drop is T'= 15 degrees .
The expression for the final value of the temperature is,
[tex]T_f=T-T^{\prime}[/tex]Substitute the given values in the above expression.
[tex]\begin{gathered} T_f=31^{\circ}F-15^{\circ}F \\ =16^{\circ}F \end{gathered}[/tex]Thus, the final temperature is 16 degrees Fahrenheit.
