conversations.value: Can you give me some step-by-step instructions for this math problem: Jenny makes and freezes pans of lasagna all week so she can sell them at the market on the weekend.  It costs Jenny $10.00 in ingredients to make 1 pan of lasagna.  If she makes and sells 20 pans over the weekend at $25.00 apiece, how much does she make after factoring in expenses?

conversations.value: Each pan costs $10.00 to make so for 20 pans, it will cost 10*20 = $200.00
  She sells each of the 20 pans for $25.00 each so she will make 20*25 = $500.00
  She makes $500.00 and spent $200.00 on ingredients so she makes 500-200 = $300.00
