Question

In Washington DC, the tax on a property assessed at $370,000 is $4,070. If tax rates are proportional in this city, how much would the tax be on a property assessed at $390,000?

Answer 1

`\$4,290`

Step-by-step explanation

The ratio of the tax to the value of the property is constant.

Let the amount of tax on the property assessed at $390,000 be x.

This implies that:

`(4,070)/(370,000)=(x)/(390,000)`

Solving for x, we have that:

`\begin{gathered} 4,070\cdot390,000=x\cdot370,000 \\ \Rightarrow x=(4,070\cdot390,000)/(370,000) \\ x=\$4,290 \end{gathered}`

That is the amount of tax on the property.
