Summary

The solution to a linear system is when all the lines intersect at one point which is called the point of intersection. In this situation, knowing the solution is important because you can use it to tell which pet food is cheaper, and when it is cheaper. So, from the solution, we know that the Puppy Munch is cheaper if you are buying less than 2.5 kg of pet food, and Kitty Dinner is cheaper if you are buying more than 2.5 kg. The prices are the same ($12.50) for both Kitty Dinner and Puppy Munch.
