Review for Unit 2 Quiz 5: Writing and Solving Equations

Sarah went to the arcade and paid $4 to buy a game card and $6.25 for each game she played. The total amount Sarah spent on the card and games is $34.75. Which equation can be used to determine the number of games, y, that Sarah played?

• 6.25y + 4.00 = 34.75

• 6.25y − 4.00 = 34.75

• 4.00y + 6.25 = 34.75

• 4.00y − 6.25 = 34.75
