To simplify the expression \(8 + 7 \cdot 6 - 3 \cdot 4 + 6 \cdot 7\), we need to use the order of operations (PEMDAS/BODMAS).

  1. Multiply and divide first:

    • \(7 \cdot 6 = 42\)
    • \(3 \cdot 4 = 12\)
    • \(6 \cdot 7 = 42\)

    Now substitute these values back into the expression:

    \[ 8 + 42 - 12 + 42 \]

  2. Now, proceed with addition and subtraction from left to right:

    • First, calculate \(8 + 42 = 50\)
    • Next, calculate \(50 - 12 = 38\)
    • Finally, calculate \(38 + 42 = 80\)

Therefore, the simplified result is \(80\).

The correct response is 80.
