Since the same number of Spreadsheet and Database apps sold, *[tex \LARGE x] can represent the number of either.  Then *[tex \LARGE 2x\ +\ 30] is the number of WP apps because 2x is the number of SS and DB together, plus 30.


The value of the SS apps was then *[tex \LARGE 130x], the value of the DBs, *[tex \LARGE 185x], and the value of the WPs, *[tex \LARGE 250(2x\ +\ 30)].  Add &#39;em up to get 80,850


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 130x\ +\ 185x\ +\ 250(2x\ +\ 30)\ =\ 80850]


Solve for *[tex \LARGE x]

*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
