Okay, here we have this:
Considering the provided information and equation, we are going to find an equation that will calculate the completed passes, so we obtain the following:
Then from the given equation we will solve for C and the resulting equation will be the one we are looking for, then we have:
[tex]\begin{gathered} P=\frac{8AY+330T+100C-200I}{A} \\ PA=8AY+330T+100C-200I \\ PA-8AY-330T+200I=100C \\ C=\frac{PA-8AY-330T+200I}{100} \end{gathered}[/tex]
The above equation is the one we are looking for, and it will calculate the completed passes for a quarterback with a given efficiency, number of passing yards, number of passing touchdowns, number of interceptions, and number of attempts.
