A jeweler who buys a ring from a jewelry maker for $125 marked with the price by 135% for sale in the store what is the selling price of the ring with 7.5 sales tax
marked up by 135% means
new price=original price+(original price times markup) =125+(125 times 1.35)=293.75
tax
293.75 times 0.075=22.03125
293.75-22.03125=271.718 so aprox $271.72
selling price would be $271.72
