Solving the equation for price, as Jim suggests is the best approach if you
can do it. But it is not always possible.
One approach that I have used is to create a separate variable for price.
Then create a loop that will step through a series of price values such
that you test each value of the price variable to see where the result
switches.
This can be tricky since many functions ("series functions") you may want
to use will not allow variables as inputs but it works well if you can work
around this problem.
