Final answer:
To evaluate the numerical expression, follow the order of operations (PEMDAS) and solve the expression inside the parentheses first. Multiply the result by the number outside the parentheses, and then subtract any remaining numbers.
Step-by-step explanation:
To evaluate each numerical expression, follow the order of operations: parentheses, exponents, multiplication, division, addition, and subtraction (PEMDAS).
For the first expression, start by solving the expression inside the parentheses: (2 × 2.4) + 3.2 = 4.8 + 3.2 = 8.
Then, multiply 15.5 by the result from the previous step: 0 15.5 × 8 = 124.
Finally, subtract 24 from the result: 124 - 24 = 100.
The answer is 100.
