The owner of an electronics store determines that the montly demand d (in units) for a computer varies inversely with the price p (in dollars) of the computer. When the price is $700, the monthly demand is 250 units. Write the invrse variation equation that relates p and d.

Then find the montly demand when the price is $500. JUST WRITE THE NUMBER, DON'T NEED UNITS!
