To solve the equation \( 50.3(n + 9.25) = -120.72 \), we can start by dividing both sides by 50.3 to isolate the term with \( n \).
-
Divide both sides by 50.3: \[ n + 9.25 = \frac{-120.72}{50.3} \]
-
Calculate \( \frac{-120.72}{50.3} \): \[ n + 9.25 \approx -2.4 \]
-
Now, isolate \( n \) by subtracting 9.25 from both sides: \[ n \approx -2.4 - 9.25 \]
-
Calculate \( -2.4 - 9.25 \): \[ n \approx -11.65 \]
Thus, the solution is: \[ n \approx -11.65 \]
The correct answer is \(-11.65\) (negative 11.65).
