D. 35.5

Answer :

Let's evaluate the expression [tex]\((4 + 2^2) \cdot (1 - 0.5)\)[/tex] step-by-step:

1. Calculate the exponentiation:
[tex]\[
2^2 = 4
\][/tex]

2. Add the result to 4:
[tex]\[
4 + 4 = 8
\][/tex]

3. Calculate the subtraction:
[tex]\[
1 - 0.5 = 0.5
\][/tex]

4. Multiply the results of the two operations:
[tex]\[
8 \cdot 0.5 = 4.0
\][/tex]

So, the final result of the expression [tex]\((4 + 2^2) \cdot (1 - 0.5)\)[/tex] is 4.0.

The correct option is [tex]\(A\)[/tex] 4.
