Answer 1

Answer: she played 5 games and went on 8 rides

Step-by-step explanation:

Let x represent the number of games that Sydney played.

Let y represent the number of rides that Sydney went on.

Each game cost $1.25 and each ride cost $2.25. If Sydney spent $24.25 altogether at the carnival, then the expression is

1.25x + 2.25y = 24.25- - - - - - - - - - -1

If the number of rides that she went on is 3 more than the number of games that she played, the expression would be

y = x + 3

Substituting y = x + 3 into equation 1, it becomes

1.25x + 2.25(x + 3) = 24.25

1.25x + 2.25x + 6.75 = 24.25

3.5x = 24.25 - 6.75

3.5x = 17.5

x = 17.5/3.5

x = 5

y = x + 3 = 5 + 3

y = 8
