Question 1186840
.
In a city, the owner of a house valued at 470 thousand dollars needs to pay $1,287.80 in property tax. 
At this tax rate, how much property tax should the owner pay if a house is valued at 780 thousand dollars? How do I solve this?
~~~~~~~~~~~~~~~~


<pre>
Since the tax rate is the same, you can write and use this propotion


    {{{1287.80/470000}}} = {{{x/780000}}},


which exactly express that the rate is the same.


From the proportion,    x = {{{(1287.80*780000)/470000}}} = 2137.20  dollars.   <U>ANSWER</U>
</pre>

Solved and explained.
