At a charity fund raiser, adult tickets were sold for $11 each and children’s tickets were sold for $5 each. If a total of 637 tickets were sold, and 4667 was raised, how many tickets of each kind were sold?
+36916 a = adult tix value = 11a
c = child tix = (637-a) value = 5 ( 637-a) summed = 4667
11a + 5 ( 637-a) = 4667
solve for a then c = 637-a
