    Answer:

    77.1 feet

    Step-by-step explanation:

    Scale model:

    Height = 18 inches

    Width = 2.5 inches

    Actual monument:

    Height = 555 feet

    Width = x feet

    Write a proportion:

    \dfrac{\text{Scale height}}{\text{Actual height}}=\dfrac{\text{Scale width}}{\text{Actual width}}\\ \\ \\\dfrac{18 \ inches}{555\ feet}=\dfrac{2.5\ inches}{x\ inches}\\ \\ \\x=\dfrac{555\ feet\cdot 2.5\ inches}{18\ inches}\approx 77.1\ feet
