To solve this, we need to calculate the total number of paws and then subtract the total number of white paws. Each puppy has 4 paws, so with 77 puppies, there are 77 * 4 = 308 paws in total. For the white paws: - 17 puppies have 3 white paws each, totaling 17 * 3 = 51 white paws. - 18 puppies have 2 white paws each, totaling 18 * 2 = 36 white paws. - 42 puppies have 1 white paw each, totaling 42 * 1 = 42 white paws. Adding these together gives 51 + 36 + 42 = 129 white paws. Subtracting the white paws from the total gives 308 - 129 = 179 black paws.
