A rational expression is a ratio of two polynomials. To add or subtract two rational expressions with the same denominator, we simply add or subtract the numerators and write the result over the common denominator. When the denominators are not the same, we must manipulate them so that they become the same.
Answer:
$99/$115 x 100% = 86.086% of the original price
So 100% - 86.086
= 13.9 = 14%
Or you could just do (115 - 99) x 100 which gets the same answer.
