Final answer:
The inequality that represents the company's goal of making at least $320 in profit from standard and deluxe flashlights is 3s + 4d ≥ 320.
Step-by-step explanation:
The company makes a profit of $3 on each standard model (s) and $4 on each deluxe model (d). If the company wants to make a profit of at least $320, the inequalities that represent this situation are 3s + 4d ≥ 320. This is because the company needs to make a minimum of $320, which translates to selling a combination of standard and deluxe flashlights where the total profit from selling s standard flashlights and d deluxe flashlights should be at least $320.
