The number of television sets that consumers buy depends on price. The higher the price, the fewer TVs people will buy. The equation that relates price to the number of TVs sold at that price is called a demand equation. If the demand equation for a 13-inch TV is 
, where p is the price and q is the number of TVs sold at that price, how many TVs will be sold at a price of $159?
