Question is about how much IN SALES, or for the example, the revenue.
Simple Arithmetic.


system%28p-3m=25%2Cp%2Bm=393%29
Try to use Elimination Method.

Martha, $92
Priscilla, $301

priscill's minus martha's was 25
and priscilla's plus martha's was 393.

If you want to start and use some simple algebra, then
system%28p-m=25%2Cp%2Bm=393%29
and you can easily use Elimination Method.

You'll NEVER find the right answer with that dude's equations. One/both DOESN'T/DON'T fit the description. 

Therefore, cross%28system%28p-m=25%2Cp%2Bm=393%29%29
