First in with the correct answer to last Trivia was CMSgt (Ret) Don Holland. 0.25 In one hour, the large inlet pipe fills 1 / 1 of the tank; the small inlet pipe fills 1 / 5 of the tank; the outlet pipe empties 1 / 6 of the tank; and therefore all three pipes together fill [ (1 / 1) + (1 / 5) - (1 / 6) ] of the tank. Fraction of the tank that will be filled in 0.24 hours = 0.24 [ (1 / 1) + (1 / 5) - (1 / 6) ] = 0.25. And there you have it!
The 10" pizza sells for $ 5.99 at my favorite pizza store. The store claims they have a great deal on the large 12" pizza, which is specially priced at $ 6.47. What is the per cent discount the store is offering?
