Gina wanted to swim at the pool. She is allowed to spend at most $30. The cost to swim in the pool is 3 dollars per hour plus a flat fee of $3. How many hours can Gina swim without going over her spending limit?

This problem can be represented by $3x+3\leq 30$ .

'x' would be the number of hours. "At most" means less than or equal to. So, the value of x would have to be less than or equal to 30.

$3x+3\leq 30-3\\\\3x\leq 27\\\\3x/3\leq 27/3\\\\\boxed{x\leq9}$

So, Gina would have a maximum of 9 hours to swim in the pool.

Hope this helps.
