Valentina's parents are planning a trip to the Typhoon Towers resort. They plan to get a 6-day Fun Pass, which will give Valentina access to all the slides and pools at the resort during their stay. Her parents also plan to get her a $30 arcade pass. Altogether, Valentina's parents will spend $129 on passes. What is the daily cost of a Fun Pass?

Answer 1

Let's assume the daily cost of a Fun Pass is x.
Valentina's parents will be at the resort for 6 days, so they will spend 6x dollars on fun passes.
In addition to the fun passes, Valentina's parents will spend 30 dollars on an arcade pass.
So, 6x + 30 = 129 dollars.
Subtracting 30 from both sides of the equation, we get 6x = 99.
Dividing both sides of the equation by 6, we get x = 99/6 = <<99/6=16.5>>16.5 dollars.
Therefore, the daily cost of a Fun Pass is $16.5. Answer: \boxed{16.5}.
