In Chicago, the tax on a property assessed at $580,000 is $8,700. If tax rates are proportional in this city, how much would the tax be on a property assessed at $350,000?

Step-by-step explanation:

Find out what percent 8,700 is of 580,000 and apply the same percentage to 450,000.

Take 15% of 350,000, which is the same as multiplying by 0.015 and get

0.015 x $350,000 = $52,500

The tax is $52,500.
