Suppose one of your elementary school students was having trouble solving the following problem and asked for help: "Tuana gave half of her marbles away. If she gave some to her sister and twice as many to her brother, and had 6 marbles left, how many marbles did she give to her brother?" List two suggestions you can give this student to help her solve this problem

1. Demand and Supply Curves and Equilibrium The table below provides a hypothetical demand and supply curve for baklava (pastry) in the town of Ruthenia. Price per piece Quantity demanded Quantity supplied (thousands of pieces per day) (thousands of pieces per day) $6.00 0 24 $5.50 3 21 $5.00 6 18 $4.50 9 15 $4.00 12 12 $3.50 15 9 $3.00 18 6 $2.50 21 3 A. Graph the supply and demand curves B. Label the equilibrium price and the equilibrium quantity on the graph. C. Suppose that a price is imposed at $3.50 (price ceiling) per piece. What is the quantity demanded ? What is the quantity supplied? This information implies that at $3.50 per piece there is (shortage/surplus/equilibrium in the market) D. Suppose that a price is imposed at $5.50 (price floor) per piece. What is the quantity demanded ? What is the quantity supplied? This information implies that at $5.50 per piece there is (shortage/surplus/equilibrium in the market)
