Veronica's Multi-Job Budgeting and Income Strategy
Based on Veronica's work and budget scenario, recall the mathematical properties and structure of her algebraic model. In your response, address the following three points:
- Write down the linear inequality in two variables that represents Veronica's weekly income requirement.
- Recall and state whether the boundary line of this inequality should be drawn as solid or dashed when graphed, and explain the mathematical reason for your choice.
- Determine whether the region representing her valid combinations of hours should be shaded above or below the boundary line, and explain how you would verify this using the test point (0, 0).

Veronica works two part-time jobs to meet her weekly budget requirements. She earns per hour at a day spa (where is the number of hours worked) and {}17.50 per hour as an administrative assistant (where is the number of hours worked). To cover her expenses, she must earn a minimum of per week. Her situation is modeled by the linear inequality .
Match each component of this algebraic model to its corresponding real-world meaning in Veronica's financial plan.
Veronica uses the linear inequality to plan her weekly work schedule across two jobs. When she graphs this inequality to visualize her options, what do the coordinates (x, y) of any point located in the shaded solution region represent?
In the context of Veronica's income model, she uses the linear inequality to represent her goal of earning a minimum of per week. True or False: When graphing this inequality, the boundary line should be drawn as a solid line to show that earning exactly is a valid solution.
Veronica is planning her weekly work schedule to ensure she earns a minimum of 280 dollars. She uses the inequality to model her income from two jobs. To visualize her options on a graph, she needs to convert this inequality into slope-intercept form (). Arrange the following algebraic steps in the correct order to complete the conversion.
Recalling the Algebraic Model for Veronica's Income
Veronica is managing her work hours across two part-time jobs to meet her weekly budget. She models her income requirement using the linear inequality , which can be rewritten in slope-intercept form as . Because her weekly earnings must be greater than or equal to her budget goal, the set of all valid combinations of hours she can work is represented on a coordinate plane by shading the region ____ the solid boundary line.
