Based on your work, the demand and supply equations are: Q_D = 100 - 10P Q_S = 40 + 20P Question 3: Step 1: Find the quantity demanded (Q_D) when the price (P) is 0. Substitute P=0 into the demand equation: Q_D = 100 - 10(0) Q_D = 100 - 0 Q_D = 100 Step 2: Find the quantity supplied (Q_S) when the price (P) is 0. Substitute P=0 into the supply equation: Q_S = 40 + 20(0) Q_S = 40 + 0 Q_S = 40 At a price of 0, the quantity demanded is 100 units and the quantity supplied is 40 units. Question 4: Step 1: Find the quantity demanded (Q_D) when the price (P) is 4.00. Substitute P=4 into the demand equation: Q_D = 100 - 10(4) Q_D = 100 - 40 Q_D = 60 Step 2: Find the quantity supplied (Q_S) when the price (P) is 4.00. Substitute P=4 into the supply equation: Q_S = 40 + 20(4) Q_S = 40 + 80 Q_S = 120 Step 3: Compare quantity demanded and quantity supplied. At a price of 4.00, the quantity demanded is 60 units and the quantity supplied is 120 units. Since Q_S > Q_D, there is a surplus. Surplus = Q_S - Q_D = 120 - 60 = 60 units There is a surplus of 60 units. Send me the next one 📸
