Answer :
25% because 27.30/36.40 is 75%. That means that 75% is what you paid.
(original number - new number) / original number......* 100
(36.40 - 27.30) / 36.40 =
9.10 / 35.40 = 0.25
to turn to a percent, multiply by 100 = (0.25 x 100) = 25%
(36.40 - 27.30) / 36.40 =
9.10 / 35.40 = 0.25
to turn to a percent, multiply by 100 = (0.25 x 100) = 25%
