Determine What Signs on Values of X and Y Would

Determine what signs on values of x and y would make the statement true. Assume that x and y are not 0.
-Use the formula $$\text { Passing Rating } \approx 85.68 \left( \frac { \mathrm { C } } { \mathrm { A } } \right) + 4.31 \left( \frac { \mathrm { Y } } { \mathrm { A } } \right) + 326.42 \left( \frac { \mathrm { T } } { \mathrm { A } } \right) - 419.06 \left( \frac { \mathrm { I } } { \mathrm { A } } \right) \text {, where } \mathrm { A } = \text { number of passes }$$ attempted, C= number of passes completed, Y = total number of yards gained passing, T = number of touchdown passes, and I = number of interceptions, to approximate the passing rating for C. Felix.
Round to the nearest tenth. $$\begin{array} { l r r r r c } \hline \text { Quarterback } & \text { A } & \text { C } & \text { Y } & \text { T } & \text { I } \\\hline \text { A. Smith } & 438 & 237 & 3062 & 21 & 7 \\\text { B. Jones } & 477 & 270 & 3157 & 25 & 10 \\\text { C. Felix } & 696 & 342 & 4331 & 24 & 15 \\\hline\end{array}$$

A) 85.3
B) 71.1
