Tickets to the softball game are $4 for students and $7 for adults. If $795 was made at the last game and 165 people attended, how many students were at the game?
x = # adults $ 7x = revenue from adults
(165-x) = # students $ 4 (165-x) = revenue from students summed = $ 795
7x + 4 (165-x) = 795 solve for x ...the number of adults, then 165-x = # students
