Suppose the price and supply of the watch are related by the following equation p = S(q) = 0.75q where p is the price (in dollars) and q is the quantity supplied (in hundreds) of watches. Answer parts e through g. e. Find the quantity supplied at a price of $0. At a price of $0, the supply is 0 watches. f. Find the quantity supplied at a price of $10. At a price of $10, the supply is about 1333 watches. (Round to the nearest whole number as needed.) g. Graph p =S(q) = 0.75q on the same axis used to graph p = 24- 1.25q in part d. Choose the correct graph below
