To solve the equation \( 50.3(n + 9.25) = -120.72 \), follow these steps:
-
Divide both sides by 50.3: \[ n + 9.25 = \frac{-120.72}{50.3} \]
-
Calculate the value on the right: \[ \frac{-120.72}{50.3} \approx -2.4 \] (You can use a calculator for this step if needed.)
-
Now the equation becomes: \[ n + 9.25 \approx -2.4 \]
-
Subtract 9.25 from both sides to solve for \( n \): \[ n \approx -2.4 - 9.25 \] \[ n \approx -11.65 \]
Thus, the solution for \( n \) is \( \boxed{-11.65} \).
