Supply Shift Lowers Equilibrium Price Steps:

• Add 60 kg to original supply quantities: new supply is 290 kg at $45, 250 kg at$35, 170 kg at $30.
• Demand unchanged: 170 kg at $45, 210 kg at$35, 230 kg at $30.
• At $35, demand (210 kg) < new supply (250 kg), creating a$40 surplus.
• At $30, demand (230 kg) > new supply (170 kg), creating a$60 shortage; 35.

Why C is correct:

• Law of supply and demand: rightward supply shift reduces price to clear market; $35 is where supply first exceeds demand, minimizing imbalance.

Why the others are wrong:

• A: $45 creates$120 surplus (170 demanded vs. 290 supplied), too high.
• B: $40 lacks table data; lies above$35, implying larger surplus.
• D: 60 shortage (230 demanded vs. 170 supplied), too low.

Final answer: C
