Question 1202464
.
The amount of money that a magazine pays for an article varies directly 
as the number of words in the article. If the magazine pays $720 for a 1200-word article, 
how much will be paid for an article of 1500 words?
~~~~~~~~~~~~~~~~~~~


<pre>
Write a proportion

    {{{words/dollars}}} = {{{1200/720}}} = {{{1500/x}}}.


From this proportion, find  x = {{{(720*1500)/1200}}} = {{{(720*5)/4}}} = 180*5 = 900 dollars.    <U>ANSWER</U>
</pre>

Solved.


Notice that the proportion says that the ratio  &nbsp;{{{words/dollars}}}  

remains the same &nbsp;(remains constant), &nbsp;exactly as the problem states.
