To find a baseball pitcher’s
earned run (ERA), you can use
the formula Ei = 9r, where E
represents ERA, i represents
number of innings pitched, and r
represents number of earned
runs allowed. Solve the equation
for E. What is a pitcher’s ERA if
he allows 5 earned runs in 18
innings pitched?
\$1000
Ei = 9r
E = (9r) / i
r = 5 and i = 18
E = (9 x 5) / 18
E = 45 / 18
E=5/2
