Required
Determine the equilibrium solutions
We have:


To solve this, we first equate
and
to 0.
So, we have:


Factor out R in 

Split
or 
or 
Factor out W in 

Split
or 
Solve for R


Make R the subject


When
, we have:




Collect like terms

Solve for W




When
, we have:



Collect like terms

Solve for R


So, we have:

When
, we have:





So, we have:

Hence, the points of equilibrium are:
and 
Hey there!
<span>Sqrt(300^2 + 300^2) </span>
<span>= 424.26 ft.
</span>
So the answer is 424 ft
Hope this helps!
You would divide the rate
