To find out how many passes the quarterback will attempt if he completes 15 passes, we can first determine his completion rate based on his performance in the last game.
He completed 10 out of 18 passes, which gives us a completion rate of:
Now, we want to find the number of attempts
We can cross-multiply to solve for
Calculating
So we have:
Now, divide both sides by 5:
Thus, if the quarterback completes 15 passes, he will attempt 27 passes.
