Question

.The vet told Jake that his dog, Rocco, who weighed 55 pounds, needed to lose 10 pounds. Jake started walking Rocco every day and changed the amount of food he was feeding him. Rocco lost half a pound the first week. Jake wants to determine Rocco’s weight in pounds, p, after w weeks if Rocco continues to lose weight based on his vet’s advice.
The equation of the scenario is
.

The values of p must be
.

Answer 1

P = -1.5w + 55
(pounds equals losing 1.5 lbs a week plus the starting weight)

your second question is a little vague so i’m assuming you mean the values of p every week if Rocco loses 1.5 lbs every week until the goal of 45 lbs is reached. that goes as follows:

w1: 53.5 lbs
w2: 52 lbs
w3: 50.5 lbs
w4: 49 lbs
w5: 47.5 lbs
w6: 46 lbs
w7: 44.5 lbs

so Rocco would reach the vet’s weight recommendation after 7 weeks
