Answer:
The correct answer is y=75x+200.
Explanation:
The total amount of money that it cost to join Big Red Gymnastics Academy is a $200 fee to rent the gym for birthday parties. This should be added to the annual $75 per hour. In other words, this is $75 multiplied by x, or the amount of hours that the gym is rented.
Therefore, the correct answer is y=75x+200.
