Ok, 5% = 5/100. Thus, 5% tax is equal to 0.05. The tax is equal to 0.05 * (the before tax cost = 40). Then, you add the price of the ticket back. You can take a shortcut by doing 100% + 5% = 105% * 40 = 1.05 * 40 = ?

Ms. Sue is totally correct. If you want to go a little bit simpler then: 25% off something is equal to 75/100 * (the price of the "something") because 25% = 25/100. But 25% means that you take that much off, so you need to minus 25/100 from the original percentage, ...
