No it is not, the tickets go up by 5 each time, but the fee changes the number that it goes up each time. Does that make sense?

That's a question about percentage.

Let's imagine that we want to know how much is 90% of 200. To do this calculation, we should multiply 200 by 90 and then divide the result by 100. We do that because 90% is the same thing that $\frac{90}{100} =0,9$ . So, 90% of 200 is equal to:

$\frac{200\cdot90}{100} =\\\\\frac{18000}{100} =\\\\180$

Now, imagine that you would like to know how much is 100% of 999. First, we multiply 999 by 100 and divide the result by 999. So, 100% of a number is equal to itself. That's a very important information, because it's possible to understand this:

If the percentage is less than 100%, the result is less than original number.
If the percentage is equal to 100%, the result is equal to the original number.
If the percentage is greater than 100%, the result is greater than original number.

Now, we can solve our problem! \o/

The options that the percentage is less than 100% are: 35% of 300, 62% of 182 and 89% of 525. Therefore, their answers will be less than the original number.

And, the option that the percentage is greater than 100% are: 250% of 18, 300% of 250 and 120% of 72. So, their answers will be greater than the original number.

On the image, you can see the answer in a table.

I hope I've helped. ^^
