To solve the equation \( 82.78(p + 11.892) = 72.8464 \) for \( p \), follow these steps:
-
Divide both sides by 82.78 to isolate \( (p + 11.892) \):
\[ p + 11.892 = \frac{72.8464}{82.78} \]
Calculating the right-hand side:
\[ \frac{72.8464}{82.78} \approx 0.8800 \]
-
Subtract 11.892 from both sides to solve for \( p \):
\[ p = 0.8800 - 11.892 \]
Performing the subtraction:
\[ p \approx 0.8800 - 11.892 = -11.012 \]
Thus, the solution for \( p \) is:
\[ \boxed{-11.012} \]
