Question

A dog owner is told by the veterinarian that his dog, max, is overweight and needs to lose 4 to 5 pounds in order to live a healthy life. The dog weighs 126 pounds when he is put on a special diet to aid in the weight loss. The vet predicts that the diet will allows max to lose 4 ounces per week. Max is brought to the vet every 2 weeks for a weight check. Write an equation to represent the doctors prediction, and the relationship between Max’s weight in pounds, y, and the number of times Max’s weight is checked, x, in periods of two weeks. Reduce all answers to the nearest tenth of a number

Answer 1

Answer:

126-(x/2)=y

Step-by-step explanation:

We have that x represents weight check

If the dog is losing 4 ounces per week he will lose 8 ounces every weight check it is equivalent to 1/2 pound every weight check

If x is the checks 1/2*x represents the total of pounds the dog is losing depending the total checks

In one equation, we know dog´s first weight= 126 pounds

Then the equation is:

126-1/2*x=y

126-x/2=y

"y" being the final max weight depending on total weight checks
