The notation \( f(30) = 150 \) indicates that if Mrs. Vega has 30 guests at her dinner party, she should serve 150 ounces of roasted potatoes. This means that the function \( f(x) \) that represents the recommended amount of potatoes is such that for every 30 guests, the appropriate quantity is 150 ounces. Thus, it helps her determine the right amount of potatoes to prepare based on the number of guests expected.
