Correct answer: B

Step 1: Replace each symbol with its given meaning.

Original expression: 56 − 8 × 5 ÷ 4 + 7

After substitution the expression becomes: 56 ÷ 8 − 5 + 4 × 7

  1. Evaluate multiplication first: 4 × 7 = 28.

  2. Evaluate division next: 56 ÷ 8 = 7.

  3. Perform subtraction: 7 − 5 = 2.

  4. Perform the final addition: 2 + 28 = 30.
