Question 955236
there are a total of 100 tickets sold for a movie. adult tickets are $12 each, childrens tickets are $8 each. the theater made a total of $880. how many childrens tickets were sold? adult tickets?
-----
Equations:
a + c = 100 tickets
12a+8c = 880 dollars
-------------------------
Modify for  elimination:
4a + 4c = 400
6a + 4c = 440
---------------------
Subtract and solve for "a":
2a = 40
a = 40 (# of adult tickets sold)
----
c = 100-40 = 60 (# of children tickets sold)
