Beatrice uses the symbol ≥ (greater than or equal to) in this inequality because she wants to ensure that the total cost of the cake and food catered from the restaurant will be at least $45. By using the symbol ≥, Beatrice is indicating that the total cost should be $45 or more. If she used the symbol > (greater than), it would mean that the total cost could be any amount greater than $45, which is not what she wants. Using the symbol ≤ (less than or equal to) would allow for the total cost to be less than $45, which is also not what she wants. Therefore, the symbol ≥ is the correct choice in this situation.
