Final answer:
The inequality modeling a company's forecast where monthly income is at least $5000 more than expenditures is y ≥ x + 5000, with x representing expenditures and y representing income.
Step-by-step explanation:
The question asks for an inequality that models a company's profit forecast, where the monthly income is at least $5000 more than the expenditures.
With x representing expenditures and y representing income for the same month, we can express this situation as the inequality y ≥ x + 5000.
This inequality indicates that the income (y) is equal to or greater than the expenditures (x) plus $5000, and it is formatted in slope-intercept form where the slope is 1 (since for every dollar increase in x, y also increases by one dollar) and the intercept is $5000, which is the minimum profit forecasted per month.
