Answer: 11.67 pounds
Step-by-step explanation:
From the question, the person have four dogs whose average weight is 63 pounds. Then, the total weight of the dogs will be:
= 63 pounds × 4
= 252 pounds
There are also three cats and the average weight of all seven of my animals is 41 pounds. This means that the total animals have a title weight of:
= 41 pounds × 7
= 287 pounds.
To get the weight of the cats, we subtract the total dog's weight from that of the whole animals. This will be:
= 287 - 252
= 35 pounds.
Since there are 3 cats, their average weight will be:
= 35/3
= 11.67 pounds
The average weight of the cats is 11.67 pounds.
