Question 1168443
<font face="Times New Roman" size="+2">


Let *[tex \Large V] represent the variable cost for either situation, let *[tex \Large F] represent the fixed cost for either situation and then let *[tex \Large x] represent the quantity that causes the variable cost to change.


Write two Cost functions of the form:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ C_i(x)\ =\ V_ix\ +\ F_i]


Where *[tex \Large i\ \in\ \{1,2\}] representing the index number of the situation you are trying to model.  Since you are interested in the value of *[tex \Large x] that makes the costs equal, set the two right-hand sides equal to each other and solve for *[tex \Large x]
