Answer:
16 2/3 %
Step-by-step explanation:
Since the price went down, we are find the percent decrease.
Percent decrease = (original price - new price)/ original price
                                = (90 - 75)/90
                                 =15/90
                                   .1666666666666
Changing to percent form
                                       16.6666666666666666666666%
                                        16 2/3 %
