Demand. Two business students decided to open a small company together to sell the own brand of sneakers. After doing some research, they estimated that the wholesale price of their product p (in dollars) would be related to the monthly supply x (in hundreds of pairs) by the equation 20 x2 + p2 = 3700 How fast is the quantity demanded changing when the unit price (per pair of sneakers) is $70 dollars, the monthly supply is x = 10 and the unit price is increasing at a rate of $4 dollars per month? Note: Enter your solution as a decimal rounded to four (4) decimal places without units.
