A Wind Chill Temperature Is a Measure of How Cold $W$

A wind chill temperature is a measure of how cold it feels outside. The wind chill temperature $W$ (in degrees Fahrenheit) is given by $W = 35.75 + 0.6215 T - 35.75 v ^ { 0.16 } + 0.4275 T v ^ { 0.16 }$ where $T$ is the actual temperature (in degrees Fahrenheit) and $v$ is the wind speed (in miles per hour) . Find the wind chill temperature for the given conditions below. Actual temperature: $15 ^ { \circ } F,$ wind speed: $10$ mph

A) $- 16.0 ^ { \circ } \mathrm { F }$
B) $68.8 ^ { \circ } F$
C) $2.7 ^ { \circ } \mathrm { F }$
D) $- 5.6 ^ { \circ } F$
E) $106.0 ^ { \circ } \mathrm { F }$
