The local community theater sold a total of 240 tickets for Saturday night’s performance. They sold 180 more full-price tickets than discount tickets. Which system of equations can be used to model this situation?

Let f represent full-price tickets and d represent discount tickets. Since 240 tickets were sold altogether, f + d = 240. “180 more full-price tickets than discount tickets” means f − d = 180, so the correct system is the one in choice D.
