Q. Brenna is in the orchestra at her school. Both the orchestra and the band, along with any parents who want to go, are taking a field trip to a symphony. The orchestra purchases 2424 student tickets and 88 adult tickets for $512\$512. The band purchases 3030 student tickets and 1515 adult tickets for $765\$765. This system of equations can be used to represent the situation:\newline24x+8y=51224x + 8y = 512\newline30x+15y=76530x + 15y = 765\newlineWhich statement is correct?\newline(A) In the system of equations, xx represents the price of an adult ticket, and yy represents the price of a student ticket.\newline(B) In the system of equations, xx represents the total amount the band and orchestra spend on adult tickets, and yy represents the total amount they spend on student tickets.\newline(C) In the system of equations, xx represents the total amount the band and orchestra spend on student tickets, and yy represents the total amount they spend on adult tickets.\newline(D) In the system of equations, xx represents the price of a student ticket, and yy represents the price of an adult ticket.\newlineWhat is the total amount of money the band and orchestra spend on student tickets?\newline88448855
  1. Identify Statement: Identify the correct statement from the choices provided. Analyze the equations to determine what xx and yy represent based on the context of the problem.
  2. Elimination Method: Solve the system of equations to find the values of xx and yy. Start by using the elimination method to eliminate yy and solve for xx. Multiply the first equation by 1515 and the second by 88.
  3. Solve for xx: Subtract the second equation from the first to solve for xx.
  4. Substitute for yy: Substitute x=13x = 13 back into one of the original equations to solve for yy. Use the first equation for substitution.
  5. Calculate Total Amount: Calculate the total amount spent on student tickets by both the band and the orchestra using the value of xx.
