Question 1025626
 The zoo charges $14 for each adult ticket and $3 for each child. The total bill for 196 people was $1039. How many adults and how many children went. 
-------
Quantity Eq:: a + c = 196
Value Eq:::: 14a+3c = 1039
--------------------------------
Modify for elimination::
3a + 3c = 3*196
14a + 3c = 1039
-------------------------
Subtract and solve for "a"::
11a = 451
a = 41 (# of adults)
c = 196-41 = 155 (# of children)
----------------
