Algebra 1 CA 2 Review

Homer sells tickets for admission to your school play and collects a total of $104. Admission prices are $6 for adults and $4 for children. He sold 21 tickets total. Write a system to represent this situation assuming "a" represents # of adult tickets and "c" represents # of children's tickets.

• a + c = 21

  6a + 4c = 104

• a + c = 104

  6a + 4c = 21

• a + c = 21

  6c + 4a = 104

• a + c = 104

  6c + 4a = 21

David is running a concession stand at a soccer game. He sells nachos and sodas. Nachos cost $1.50 each and sodas cost $0.50 each. At the end of the game, David made a total of $78.50 and sold a total of 87 nachos and sodas combined. Which system of equations represents this situation? *

• 1.5x + 0.5y = 78.5

  x + y = 87

• 1.5x + 0.5y = 78.5

  1.5x + 0.5y = 87

• x + y = 78.5

  1.5x + 0.5y = 87

• x + y = 78.5

  x + y = 87

Flagship Cinemas sells movie tickets that are $4 for matinees and $7 for regular. One night, the theater sells 578 tickets and collects $3365 in total ticket sales.

Which system best represents the situation?

• 4m + 7r = 578

  r + m = 3365

• 4m + 7r = 3365

  r + m = 578

• 4r + 7m = 578

  r + m = 3365

• 4r + 7m = 3365

  r + m = 578

What is the x-intercept for the given graph?

• 1
• -2
