Solve the Problem $\mathrm { T } = 0.113 \mathrm { x }$

Solve the problem.
-As the relative humidity increases, the temperature seems higher than it is. The formula $\mathrm { T } = 0.113 \mathrm { x }$ + $82.57$ approximates the apparent temperature for an actual temperature of $90 ^ { \circ } \mathrm { F }$ , where $\mathrm { x }$ is the relative humidity. What is the apparent temperature (to the nearest degree) for a relative humidity of $50 \%$ ?

A) $88 ^ { \circ } \mathrm { F }$
B) $467 ^ { \circ } \mathrm { F }$
C) $83 ^ { \circ } \mathrm { F }$
D) $133 ^ { \circ } \mathrm { F }$
