The Owls band and choir held a concert as a fundraiser for an upcoming trip. Tickets to the show were $7 for adults $4 for students. A total of 150 tickets were sold and a total of $900 was raised. Which of the following equations would best represent this situation?

• a. 7x + 4y = 900 x + y = 150

• b. y = 7x + 900 y = 4x + 150

• c. y = 7x + 150 y = 4x + 900

• d. 5x + 2y = 400 x + y = 100
