    Answer:

    D) (70 + 65) + 80

    Step-by-step explanation:

    70 + (65 + 80) = 215

    A) (70 + 65) × (70 + 80) = 135 × 150 = 20,250

    B) (70 × 65) + (70 × 80) = 4,550 + 5,600 = 10,150

    C) (70 × 65) + 80 = 4,550 + 80 = 5,030

    D) (70 + 65) + 80 = 135 + 80 = 215

    E) None of the above
