Polynomial equations have a finite number of solutions that vary from none to the degree of the polynomial. However, linear inequalities most of the time have an infinite number of solutions. Compare and contrast two real-world examples of problems that have a finite number of solutions versus a problem that perhaps has infinite solutions.
