conversations.value: I'm completely lost with this math problem: An animal shelter is having a pet adoption event where owners can adopt an animal for just the cost of the vet fees. Vet fees for dogs are $15, and vet fees for cats are $13. Eight families adopt dogs and three adopt cats. The vet donates a third of the fees they were paid for the adoption checkups back to the shelter. How many dollars did the vet donate?
  Can you give me a hand?

conversations.value: The vet made 8 * 15 = $120 in dog vet fees.
  The vet made 3 * 13 = $39 in cat vet fees.
  The total vet fees were 120 + 39 = $159.
  The vet donated 1/3 of the fees, so they donated 159 / 3 = $53 back to the shelter.
