To solve for \( n \) in the equation:
\[ 50.3(n + 9.25) = -120.72 \]
First, divide both sides by \( 50.3 \):
\[ n + 9.25 = \frac{-120.72}{50.3} \]
Calculating the right side:
\[ \frac{-120.72}{50.3} \approx -2.4 \]
So the equation now becomes:
\[ n + 9.25 = -2.4 \]
Next, solve for \( n \) by subtracting \( 9.25 \) from both sides:
\[ n = -2.4 - 9.25 \]
Calculating that gives:
\[ n = -11.65 \]
So the solution is:
\[ \boxed{-11.65} \]
Thus, the correct response is \( -11.65 \) (negative 11.65).
