To solve for p, we need to isolate p on one side of the equation. Here are the steps to solve the equation:
1. Begin with the given equation: 82.78(p+11.892)=72.8464
2. Distribute 82.78 to both terms inside the parentheses: 82.78p + 82.78(11.892) = 72.8464
3. Perform the multiplication within the parentheses: 82.78p + 985.05616 = 72.8464
4. Subtract 985.05616 from both sides of the equation: 82.78p = 72.8464 - 985.05616
5. Simplify the right side: 82.78p = -912.20976
6. Divide both sides of the equation by 82.78: p = -912.20976 / 82.78
Therefore, the solution for p is p = -11.0123 (rounded to 4 decimal places).
