    You are going to have to compare the height and shadow of Julia to the height and shadow of the flagpole.

    Julia is 5 feet tall with a shadow of 7 feet.

    The flagpole is "x" feet tall with a shadow of 35 feet (to get 35, I added 28 feet and 7 feet.)

    So, you do 5/7 = x/35

    You cross multiply and get 175 = 7x

    Then, divide by 7 and you get 25.

    25 feet is the height of the flagpole, so it would be option "D".
