Question

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?

Answer 1

x+y = 87

1.5x+0.5y = 78.5

Explanation:

Let x = number of nachos sold and y = number of sodas sold

x+y = 87 because that's the total number of nachos and sodas he sold

1.5x+0.5y = 78.5 because nachos cost $1.50 and sodas cost $0.50 and David made a total of $78.50
