The selling price of an item is $520. After 6 months of not selling, it is marked down by 20%. After another another 6 months of not selling, it is further marked down by 30%. Find the sale price after both markdowns. Could you just tell me the steps and maybe give an example to this? Thank you.

Respuesta :

if y is orginal price and its decreased by 20 percent , first you have to find 20% of y, which is (20/100 × y) and you will subtract this from the original price to get the decreased price of the item. so finak formula becomes y - (20/100 × y) , you can use any percent , 20 percent is just an example...
