2. 0.1 ml of a bacterial culture was pipetted into a 9.9 ml dilution blank, 0.1 ml of this dilution was pipetted into a 9.9 ml dilution blank. From this dilution, 0.1 ml was plated. 145 colonies arose after incubation. How many colony-forming units were present per mL of the original culture? Show your work. 0. 1 ML 0. 1 ML 0. 1mL 9. 9 ML 9. 9 ML 0. 1 Undilute $10^{-1}$ $10^{-2}$ $10^{-3}$ CFU/mL = Colonies counted 145 colonies Plate $\frac{1}{10^{-3}} \times \frac{1}{0.1} = 10^5$ $145 \times 10^5 = 1.45 \times 10^5$ CFU/mL

Scenario: Instead of a price ceiling, suppose the government introduces a subsidy of $5 per toy. Task: 1. Adjust the supply equation to reflect this subsidy. 2. Find the new equilibrium price and quantity. 3. Calculate the new consumer surplus, producer surplus, and total surplus. 4. Analyze the impact of the subsidy on welfare. 2 Hints: • Adjusted supply equation: QS = −20 + 4(P + 5). • Find new equilibrium using the adjusted supply and original demand equations. • Calculate new surpluses using the area of triangles method.
