9 Which of the following functions could be considered as an example of relationship between the quantity supplied Q and market price p? (2 Points) O Q= -3p+9 O Q=5/P O Q= P12 O Q = 2+ p^(-2) O Q = exp(-p).10. Which of the following would cause a shift in supply? A. The income level of consumers changes B. The price of production inputs changes C. The production technology changes (2 Points) r). (A) Only A is true /'\\ '3 (B) Only B is true /_'\\ '3 (C) Only C is true /_'\\ " ,." (D) A and C are true /\"\\ " (E) B and C are true Equilibrium occurs where: (2 Points) (A) the quantity supplied and the quantity demanded are the same for a given price (B) the quantity supplied is greater than the quantity demanded (C) the quantity demanded is greater than the quantity supplied (D) suppliers want to change their behaviour (E) customers want to change their behaviour BapMaHT 2 The demand curve for widgets is given by D = 85 - 5P and the supply curve is given by S = 25 + 5P, where P is the price of widgets. When the widget market is in equilibrium, the quantity of widgets bought and sold is (2 Points) 0 6 O 11 30 55 80 13 If the demand for good Y and its supply have increased, [) (2 Points) O (A) the equilibrium price of Y rises; O (B) the equilibrium price of Y falls; (C) the equilibrium price of Y will not change; (D) it is impossible to make a definite conclusion regarding new equilibrium price. O (E) Quantity fallsIf supply and demand both decrease simultaneously, which of the following will happen? (2 Points) '1'??? (A) Price will rise /'\\ '1 1' (B) Quantity sold will rise A .; ;. (C) Price Will fall A .; ;. (D) Quantity sold will decrease /'_'\\ " _ -. (E) The quantity change is unclear If the market demand for a good decreases, and the supply increases, then (2 Points) 0 (A) equilibrium quantity decreases A '13' (B) equilibrium price decreases A ._."

The net effect of the two increases would be the following change in equilibrium price and quantity: (2 Points) A (A) an increase in quantity but a slight decrease in price. A (B) increases in both quantity and price. A , J (C) decreases in both quantity and price. A . (D) an increase in price but a decrease in quantity.
