Question 128278
In a game,18 of a baseball team's 27 outs were fly balls. Fifty percent of the outs made by infielders and 100% of the outs made by outfielders were fly balls. How many outs were made by outfielders? How many outs were made by infielders? Hint: write one equation for the total number of outs and another equation for the number of fly ball outs.
----------------------------
Let I be the number of infielder outs; Let O be the number of outfielder outs.
EQUATIONS:
Total # of outs equation:  I +   O   = 27
# of outs by fly-our :     I +(1/2)O = 18

------------------------------------------------------
Subtract the 2nd equation from the 1st to get:
(1/2)O = 9
O = 18 (# of outs by outfielders)
I = 27-9 = 18 (# of outs by infielders)
