Creating Inequalities with 2 Variables

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.
