A shift coordinator uses the inequality ${}15x + 25y \geq 500$ to determine how many standard deliveries ($x$) and express deliveries ($y$) are needed to meet a revenue goal. Arrange the following steps in the correct order to solve and graph this income application.

In a linear inequality application such as ${}12x + 15y \geq 300$, which models a goal of earning a minimum income of 300 dollars from two jobs (where $x$ and $y$ represent the hours worked at each job), match each graphical element to its meaning in the context of the problem.

A gig economy worker earns 15 dollars per hour delivering groceries ($x$) and 25 dollars per hour as a freelance virtual assistant ($y$). They have set a financial goal to earn at least 600 dollars this month to pay for a certification course. Which inequality correctly models the requirement to earn a minimum of 600 dollars from these two jobs?

True or False: In the linear inequality ${}10x + 15y \geq 240$, which is used to model a weekly income goal, the variables $x$ and $y$ represent the hourly pay rates for the two different jobs.

When an employee graphs a linear inequality to find valid combinations of hours across two different roles to meet a minimum income goal, any ordered pair that falls in the ____ region of the graph represents a workable schedule that satisfies the requirement.
