Big Red Gymnastics Academy charges an initial fee of $200 to rent its gym for birthday parties. The academy then charges an addi
tional $75 per hour. Write an equation that gives the total cost of the gym as a function of gym time (in hours)
y=75x+200
y=200x+75
y=200-75x
y=75x-200
The total amount of money that it cost to join Big Red Gymnastics Academy is a $200 fee to <em>rent </em>the gym for birthday parties. This should be <u>added</u> to the annual $75 <u>per hour</u>. In other words, this is $75 <u>multiplied</u> by x, or the <u><em>amount of hours</em></u> that the gym is rented.
