You are a logistics manager tasked with ordering two types of shipping materials: standard boxes ($s$) and heavy-duty crates ($c$). You must translate the operational requirements into a system of linear inequalities. You know that you need to transport at least 5,000 pounds of equipment, and you have a budget of no more than 800 dollars. Based on standard algebraic modeling rules for real-world physical items, what foundational constraints must you recall and include in your system to ensure the quantities of boxes and crates are realistic?

A project coordinator for an athletics department is planning a supplemental nutrition package for a marathon runner. Each donut ($d$) provides 360 calories and costs $0.75, while each energy drink ($e$) provides 110 calories and costs $2. The runner requires at least 1,000 extra calories per day, and the coordinator has a maximum budget of $25. Match each logistical requirement with its correct mathematical representation in the system of inequalities.

A supply chain analyst is visualizing a resource constraint modeled by the inequality ${}360d + 110e \geq 1,000$. The analyst tests the origin (0, 0) and determines that the resulting statement, ${}0 \geq 1,000$, is false. True or False: Because the test point results in a false statement, the analyst should shade the region of the graph that includes the origin to represent the solution set.

A community health program coordinator is verifying a proposed nutrition package for a marathon runner using a system of linear inequalities. Arrange the following steps in the correct mathematical order to determine if a specific combination of donuts ($d$) and energy drinks ($e$) is a valid solution.

Nutritional Coefficient Recall in Marathon Planning

An occupational health coordinator is graphing a system of linear inequalities to model nutrition and budget allocations for a workplace marathon team. One of the budget constraints is represented by the inequality ${}0.75d + 2e \leq 25$. To graph this constraint, the coordinator must draw the boundary line ${}0.75d + 2e = 25$ as a(n) ____ line because the inequality includes the 'less than or equal to' symbol.
