We are told that the dog should weigh less than
pounds. The phrase "less than" can be algebraically expressed using the symbol
Now we can write an inequality that describes the desired weight for the dog.
The current weight of the dog is
pounds and she is expected to lose
pounds per week on the new diet. If we call the number of weeks the dog has to diet
we can write the left-hand side of the inequality.
By solving for
we can find how many weeks it will take for the dog to reach her dream weight.
It's going to take more than
weeks for the dog to reach a healthy weight.
