Let's define the variables for the number of games Lauren played and the number of rides she went on.
- Let x be the number of games Lauren played.
- Let y be the number of rides Lauren went on.
The cost of playing each game is $2, so the total cost of playing x games is 2x dollars. Similarly, the cost of each ride is $4.75, so the total cost of going on y rides is 4.75y dollars.
According to the problem, Lauren spent $50 altogether at the carnival. Therefore, we can write the first equation as:
2x + 4.75y = 50
The problem also states that the number of rides Lauren went on is 2 more than the number of games she played. Therefore, we can write the second equation as:
y = x + 2
So the system of equations that could be used to determine the number of games Lauren played and the number of rides Lauren went on is:
2x + 4.75y = 50
y = x + 2
