The demand equation for a certain brand of metal alloy audiocassette tape is 
, where x represents the number (in thousands) of ten-packs demanded each week when the unit price is $p.
?
How fast is the quantity demanded increasing when the unit price/ten-pack is $20 and the selling price is dropping at the rate of $.11/ten-pack/week? Round your answer to the nearest integer.
?
Hint: To find the value of x when p = 20, solve the equation 
for x when p = 20.
