Question 548962
Let x be the salary before the raise.  
This means that she now makes 
{{{x+0.07x}}} 
which we are told is 67500

So we have:
{{{1.07*x=67500}}}


Now, we need to solve for x.   I will leave this up to you, if you are unsure how to do that please feel free to let me know and I will help you out more :)
