At the city museum, child admission is $6.00 and adult admission is $9.70. 166 tickets were sold for a total sales of $1351.20. How many child tickets were sold that day?

c = child tix                     revenue from = $ 6 c

a = adult tix = 166-c       revenue from = $ 9.70(166-c)   Summed, the two revenues total 1351,20

 

6 c   + 9.7 (166-c )    = 1351.20      solve for 'c' the number of chlid tix
