math: problem solving

During a storewide sale, a TV which usually sells for $450 is on sale for $360. A Stereo which usually sells for $600 is on sale for $480. What would be the sale price of a VCR which usually sells for $500?

The question to ask yourself is, "If the 450 item now costs 360, what percentage is that of the original price?"
450xwhat fraction = 360
fraction = 360/450 = 0.80 (so there was a 20% discount).
See if the other one is the same (I think it is if the usual selling price of 600 is on sale for 480.)
Then use that same fraction to multiply the 500 VCR to see what it would sell for. 
thanks a million! it was the same for the stereo so i just multiplyed $500 by .8 and got $400 as the sale price.

That's correct.
