Product C yields the highest profit, suggesting that focusing solely on its production could maximize

overall profits. However, business scenarios are rarely this straightforward; otherwise, tools like Solver

wouldn't be necessary. The company faces specific constraints when it comes to product production:

$$ The total daily production capacity is limited to $300$ units.

$$ There's an existing order for $50$ units of Product A that needs fulfillment.

$$ An expected order requires $40$ units of Product B$.$

$$ Due to limited market demand, the company aims to cap Product C production at $40$ units per

day.

Now, let's explore how Solver can help address these constraints and optimize the situation.
