Insufficient data to determine judge's fee Steps:

• Identify revenues: ticket sales $1500 + program sales$450 = total revenue $1950.
• Identify known expense: prize payments $250.
• Note that judge's fee is an additional expense not listed in the provided information.
• Conclude no calculation possible without judge's fee or total expenses/profit details.

Why A is correct:

• Not applicable; no option solves the problem due to missing data on judge's payment.

Why the others are wrong:

• B: Equals ticket sales minus program sales ($1500 -$450), ignores prizes.
• C: Equals total revenue minus double prizes ($1950 -$500), arbitrary adjustment.
• D: Exceeds total revenue ($1950), impossible without additional funds.

Final answer: Not enough information.
