Question

Three dogs are weighed. Dog A weighs 30 pounds, dog B weighs 50 pounds and Dog C weighs 85 pounds. What percent is dog C's weight to dog B's weight? Write the answer in decimal form.

Answer 1

if c = 6, the d= 8c = 8(6) = 48.

Explanation:

Let c = weight of cat.

Let d = weight of dog.

d = 8c (the dog weights 8 times as much as the cat)

d + c = 54 (together, they weigh 54 pounds)

Substitute 8c for d from the first equation into the second equation:

8c + c = 54

9c = 54

c = 6

if c = 6, the d= 8c = 8(6) = 48.
