Calculating Total Government Spending on Public Goods

Steps:

• Identify categories of public goods spending from the provided data (e.g., defense, education, infrastructure).
• Sum the values for each relevant category: defense ($150M) + education ($120M) + infrastructure ($73M).
• Add any other public goods like health ($0, if not specified) to get the total.
• Verify the sum: 150 + 120 + 73 = 343.

Why C is correct:

• $343 million matches the exact sum of specified public goods expenditures, per standard economic accounting of non-excludable, non-rivalrous goods.

Why the others are wrong:

• A: $230 million undercounts by omitting infrastructure spending.
• B: $450 million includes private goods like subsidies, violating public goods definition.
• D: $5740 million totals all government spending, not just public goods.

Final answer: C
