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?

• 1.5N+0.5S=78.5

  N+S=87

• 1.5N+0.5S=78.5

  1.5N+0.5S=87

• N+S=78.5

  1.5N+0.5S=87

• N+S=78.5

  N+S=87
