###Human: Marcy uses 6 ounces of pet cleaner to clean up a dog stain, 4 ounces to clean up a cat stain, and 1 ounce to clean up a rabbit stain. How much cleaner does she need to clean up after 6 dogs, 3 cats and 1 rabbit?, ### Assistant: First find the total amount of cleaner used for the dogs: 6 ounces/dog * 6 dogs = 36 ounces
Then find the total amount of cleaner used for the cats: 4 ounces/cat * 3 cats = 12 ounces
Then add the amount of cleaner used for each species to find the total amount used: 36 ounces + 12 ounces + 1 ounce = 49 ounces 
 So the answer is :  49
