The selling price of an item is 600$. After 6 months of not selling, it is marked down by 10%. After another 6 months of not selling, it is further marked down by 20%. Find the sale price after both markdowns.
well 10% of 600 is 60 so you would subtract 600-60= 540 so the first markdown would be $540 then 20% of 540 is 108 so you would subtract 540-108=432 so the second markdown would $432
