Summing all listed tax receipts

Steps:

• Add air passenger duty and tax on firms profits: 10 + 75 = 85
• Add import duties: 85 + 100 = 185
• Add inheritance tax: 185 + 50 = 235
• Add sales tax (VAT): 235 + 150 = 385

Why C is correct:

• The total is the sum of all five tax receipts in the table, which equals 385m using standard addition.

Why the others are wrong:

• A omits most receipts, only matching VAT.
• B adds VAT and inheritance tax but ignores others.
• D adds VAT, firms profits, import duties, and inheritance but overcounts by including air passenger duty twice or misadding.

Final answer: C
