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

Stefan's school is selling tickets for a music department concert. On the first day of ticket sales 3 senior citizen tickets and 1 child ticket were sold for a total of $38. On the second day 3 senior citizen tickets and 2 child tickets were sold, for a total of $52. Write a system of equations that fits this scenario.

• 1s + 3c = $38

  2s + 3c = $52

• 3s + 1c = $38

  3s + 2c = $52

• s + c = $38

  s + c = $52

• 3s + 3c = $38

  1s + 2c = $52
