A movie theater sells tickets.

· Each child ticket costs $4.50

· Each adult ticket costs $6.50

· One night they sold a total of 478 tickets

· Ticket sales were a total of $2401

Which system of equations can be used to represent this situation?

• $4.50x+6.50y=478$
  $x+y=2401$
  

• $4x+4y=478$
  $x+y=1923$
  

• $4.50x+6.50y=2401$
  $x+y=478$
  

• $4x+4y=478$
  $4x+4y=2401$
