The admission fee at a carnival fair is $4.50 for childrenand $8.00 for adults. One day, 2200 people attended the fair and $5050 was collected. How many children and how many adults attended?
a = #adults revenue = 8a
c = #children = 2200-a revenue = 4.5(2200-a) summed, the revenues add to 5050
8a + 4.5(2200-a) = 5050 solve for a, the # of adult tix then c = 2200-a
