If 
x = number of sophomores that bought tickets
what would represent the number of freshmen who bought tickets?

kropot72 · Answer

If x sophomores bought tickets and the total number of freshmen and sophomores with tickets was 150, the number of freshmen who bought tickets must be (150 - x).
Can you form an equation with the total value of x sophomore tickets plus the total value of (150 - x) freshmen tickets equals $400 ?
