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?

• x+y=78.5

  1.5x+0.5y=87

• 1.5x+0.5y=78.5

  1.5x+0.5y=87

• x+y=78.5

  x+y=87

• 1.5x+0.5y=78.5

  x+y=87
