To solve the equation \( 50.3(n + 9.25) = -120.72 \), we can follow these steps:
- Divide both sides by \( 50.3 \):
\[ n + 9.25 = \frac{-120.72}{50.3} \]
Calculating the right-hand side:
\[ \frac{-120.72}{50.3} \approx -2.4 \]
So now we have:
\[ n + 9.25 \approx -2.4 \]
- Next, isolate \( n \) by subtracting \( 9.25 \) from both sides:
\[ n \approx -2.4 - 9.25 \]
Calculating the right side:
\[ n \approx -11.65 \]
Thus, the solution is:
\[ \boxed{-11.65} \]
So the correct response from your options is \( -11.65 \).
