Astore's cost for a stereo was $27. the markup was 75%. a customer purchased it on sale at 40% off the markup price. what was the purchase price of the stereo

So the stereo costs $27, so to include a price for profit and other expenses, it gets ballooned to 75% extra, or the new price is 175%, how much is that?

if we take 27 to be the 100%, what's 175% of that?



alrite, then a customer showed up and found it on sale, 40% off that price, so if you take out 40% from the 100%, the price the customer found it at is the 60%, 100-40,  of the current price of 47.25

so, if 47.25 is the 100%, what's 60% of that?



solve for "x".
