A movie theater sold 1200 tickets and made $6400 in one night. If an adult ticket costs $7 and a children's ticket costs $3, how many adult tickets were sold? A. a + c = 1200 7a + 3c = 6400 B. a c = 1200 7a 3c = 6400 C. a + c = 6400 7a + 3c = 1200 D. a + c = 10 7a + 3c = 7600

A particular movie theater charges $6.00 per adult ticket and $5.50 per child ticket. Suppose 700 people attended a movie and the total revenue from ticket sales was $4025. Write two linear equations to represent a system to solve this, where x represents the number of adults attending the movie and y represents the number of children attending the movie. DO NOT SOLVE.
