The temperature-humidity index I (or humidex, for short) is the perceived air temperature when the actual temperature is T and the relative humidity is h, so we can write I = f (T, h). The following table of values of I is an excerpt from a table compiled by the National Oceanic and Atmospheric Administration. For what value of T is $f ( T , 50 ) = 107$ ? $$\begin{array} { | c | c | c | c | c | c | c | }
\hline \begin{array} { c }
T&h \
\downarrow&\rightarrow
\end{array} & 20 & 30 & 40 & 50 & 60 & 70 \
