Use the space below and the back to write out and clearly indicate your answers. Do not use this sheet as scrap paper, but use it to neatly present your work. Halmark and Sybi made glass paperweights back in the 20th century, and their products are now considered antiques. There are 440 existing Sybi paperweights, and the demand function for Sybi paperweights is given by Ds(PS, PH) = 1100 -5PS - PH, where Ps is the price of a Sybi paperweight and PH is the price of a Halmark paperweight. There are 1023 existing Halmark paperweights, and their demand function is given by DH (PH, PS) = 1320 - 2PH + PS- 1) Find the equilibrium prices of Sybi and Halmark paperweights. Show your work. [2pts] 2) Sketch a supply and demand diagram for each market, not necessarily to scale. Label the supply curves S and the demand curves D. [2pts] PH PS OH Qs3) Suppose a sinkhole develops at the Sybi Museum in Hamond, Kentucky and swallows up 44 of the Sybi paperweights. Calculate the new equilibrium prices of Sybi and Halmark paperweights. Show your work. [2pts] 4) Are Sybi paperweights a gross substitute or gross complement for Halmark paperweights? Explain your answer. [1pt] 5) Are Halmark paperweights a gross substitute or gross complement for Sybi paperweights? Explain your answer. [1pt] 6) Using dashed lines, show the effect of the sinkhole in your supply and demand diagrams, taking into account the gross substitute or gross complement relationships of the goods. Label the new supply curves S' and the new demand curves D'. [2pts]
