Consider the general demand function and the supply function for dates in tons below: Qd = 60 - 2p + 0.01M + 0.5r + 6Pe%3D Qs = 600 + 10OP

Qd = quantity demanded of dates in ton M = income P= price of dates in SAR Pr= price of related good(chocolate) Pe= expected price of dates Qs = quantity supplied of dates 1. Define the relationship between the price of dates and quantity demanded as well as the price and the quantitysupplied? Is it consistent with the law of demand and supply? 2. Are dates normal good or inferior good? Explain? 3. What are the determinants of demand in the general demand function above? 4. Are dates substitute with the related product (chocolate)? Explain? 5. What is the effect of the increased quantity demanded by 20 ton, on the equilibrium price and quantity demandedand supplied? Is it a movement along the demand curve or shift in the curve itself? Explain?
