The town of Centerville spends 15% of its annual budget on its public library. Centerville spent $3,000 on its public library and 24% on the public parks. How much is left of the annual budget? Let's be accurate as possible.
The entire budget of Centerville is $3000 / 0.15 = $20,000. The budget for the parks is $20,000 * 0.24 = $4,800. After the park and the library there will be $20,000 - ($3,000 + $4,800) = $12,200 left in the budget.
The answer: 12200.
