Mr. P was telling a friend about the terrible service that he received at the Walrus Restaurant in Bismarck, North Dakota. "The food was great but the server was extremely rude, so I only tipped her 14%. Instead of giving her $10.00, I only gave her $6.00." What percent would Mr. P have tipped her if he had given her $10?
Solution to the Problem:
The answer is 23.3%.Let x = the cost of the dinner.
Then .14x = 6.00
So, x = $42.86 (the cost of the dinner)
Then the percent Mr. P normally would have tipped = 10.00 / 42.86 = 23.33%.
You could have also set up a proportion to solve this problem:
14 / 6 = x / 10
x = 23.33%
