Suppose the supply and demand for a certain textbook are given by supply:p=fa, demand: p= 0 + 30, where is the price and q is the quantity. Find the demana quantity and the supply quantity at a price of $10. The number of books that are demanded at a price of 10 is and the number of books supplied at a price of $10 is (Round to the nearest whole number as needed.) Find the equilibrium quantity and equilibrium price for the commodity whose supply and demand functions are given. Supply: p= 309 Demand: p= -q? +7,000 The equilibrium quantity is q-at price p= $ Find the equilibrium quantity and equilibrium price for the commodity whose supply and demand functions are given. Supply: p = 22 +30 Demand: p= -49% + 10 + 19,200 The equilibrium quantity is q = =(Round to the nearest whole number as needed.)
