Question 328597
<font face="Garamond" size="+2">


I would have written


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ S\ =\ 2C\ +\ 200]


First of all, it more naturally follows the language of the problem.  And second, it makes finding the solution set easier because you can just set the two expressions that are equal to *[tex \LARGE S] equal to each other and solve for C.  S follows directly.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 850\ -\ C\ =\ 2C\ +\ 200]
