To find a baseball pitcher's earned run average (ERA), you can use the formula El=9r, in which E
represents ERA, I represents the number of Innings pitched, and r represents the number of earned runs allowed.
Solve the equation for E. What is a pitcher's ERA if he allows 15 earned runs in 36 innings pitched?
If necessary, round your answer to the nearest hundredth.
The equation for E is E= _____?
