Question 114568
Let x=amount spent to gain a revenue of $180,000


We simply have this relationship

<pre>

money spent on advertising     unknown amount of money spent on advertising 
-------------------------- = -----------------------------------------------
        Revenue                                 New Revenue

</pre>

So that means we have the equation


{{{2000/120000=x/180000}}}



{{{180000(2000/120000)=x}}} Multiply both sides by 180,000



{{{180000(1/60)=x}}} Reduce the fraction in the parenthesis




{{{180000/60=x}}} Multiply




{{{3000=x}}} Reduce



So when $3,000 dollars is spent on advertising, the revenue is $180,000
