I have two values that calculate to a success rate of 93.32. Total=1546051 Failures=103302. (1546051-103302)/1546051=93.32% success. Now how much would I need to increase the total value to get the success up to 95%? Answered by Stephen La Rocque.     Reverse pecentage 2005-03-01 From Nathan:Question for you. If I have spent \$10.00, what is the mathamatical equation to figure out what the G.S.T (7%) was? Also if I were to spend \$80.00 on a hotel, and I would like to know how much G.S.T (7%) and how much provincial tax (6%) I spent how would I go about this. Answered by Penny Nom.
