Lizzy: 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?.
Me: Hmmm, let me think. I think this is the detailed solution:
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. Final answer: 53.
