A pet store donated 50 pounds of food for adult dogs, puppies, and cats to an animal shelter. 17 3 4 pounds was adult dog food and 17 7 8 pounds was puppy food. How many pounds of cat food did the pet store donate?

14 3/8 pounds

Step-by-step explanation:

Given

Total pounds donated = 50 pounds

Amount for dogs D = 17 3/4 pounds

Amount for puppy P = 17  7/8 pounds

Required

Amount of cat food C

Total = D + P + C

50 = 17 3/4 + 17 7/8 + C

50 = 71/4 + 143/8 + C

50 = (142+143)/8 + C

50 = 285/8 + C

C = 50 - 285/8

C = 400-285/8

C = 115/8

C = 14 3/8

Hence the pounds of cat food donated was 14 3/8 pounds

answer: 8
