In an office building, an elevator has a maximum carrying capacity of $12750$12750 pounds. This is based on an average female's weight of $150$150 pounds and an average male's weight of $170$170 pounds.
Let $x$x represent the number of women who enter the elevator.
Let $y$y represent the number of men who enter the elevator.
Write an inequality to represent the number of men and women who can enter the elevator at one time, with $y$y as the subject.
