The City of Greenville needs to raise revenue. Alderman Black has proposed a $10 tax on red cars in the city, currently numbering 2,000. Mayor White, who wants more than $20,000 in revenue, proposes taxing these cars at $100 each. Councilwoman Bluestone goes even farther, suggesting a $1,000 per red car tax, arguing that her proposal will raise $2 million. If maximizing tax revenue is the only consideration, which proposal should pass? Why?
