conversations.value: Ken caught twice as many fish as Kendra, but Ken released 3 fish back into the lake. Kendra caught 30 fish and did not release any of them back into the lake. How many fish did Ken and Kendra bring home?
  Can you solve this problem?

conversations.value: Ken caught 30*2=60 fish.
  Ken brought home 60-3=57 fish.
  Ken and Kendra brought home 57+30=87 fish.
