(Ignore the scatter plot thing)
Since the necklace is 33% off, you subtract 33% from 100% to get 67% (you’re only paying 67% of the initial price). You can then multiply 88*0.67 to get the sale price, which is $58.96. For the markdown dollars you can subtract 58.96 from 88 to get $29.04 (you saved $29.04 from the sale)
