Question 1108944
The admission fee at a small fair is $1.50 for children and $4.00 for adults. On a certain day, 2200 people enter the fair and $5050 is collected. How many children and how many adults attended? 
======
Equations:
a + c = 2200 tickets
4a+1.5c = 5050 dollars
-------------------------------
Modify for elimination::
4a + 4c = 4*2200
4a + 1.5c = 5050
--------------------
Subtract and solve for "c":
3.5c = 3750
-------
c = 1071.43
----
Cannot be correct.  # of children must be a whole number.
