I would like to know how to find the percent of increase when the percentage is unknown.
The notion of percentage creates a great deal of episode among students. The reason for that is, because focus hinges on procedure of, how to do this and that, without paying attention to what it is?
Percentage is simply a ratio, and ratio is a fraction, is indication for comparison of 2 numbers in magnitude.
$ 9 and 3 quarters of dollars = $ 9.75 = 975 C
What is the sales Tax paid on $ 50 purchase of the rate of nine and 3 quarter of a percent.
$ 50 * 9 3/4 % = 50 * 9.75 % = 50 * 0. 0975 = $4.88
