ANSWER:

According to the vet healthy weight of the dog is 63 pounds.

SOLUTION:

Given, Sam's dog weighs 72 pounds.  

The vet suggests that for the dog's health, its weight should decrease by 12.5 percent.

Now, we need to find the healthy weight of a dog.

Healthy weight of dog = present weight of dog – 12.5 percent of its present weight

Healthy weight = 72 – 12.5 % 72

= 72 – 9  = 63 pounds

Healthy weight of the dog is 63 pounds

Hence, according to the vet healthy weight of the dog is 63 pounds.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
