B. -40.4
C. 36.6
D. -36.6

Answer :

Sure! Let's solve the expression step by step:

We want to find the value of [tex]\(13.1 - 20.2 + 9 - (-38.5)\)[/tex].

1. Start with the first two numbers:
- [tex]\(13.1 - 20.2 = -7.1\)[/tex].

2. Add the next number:
- [tex]\(-7.1 + 9 = 1.9\)[/tex].

3. Subtract the negative number:
- When you subtract a negative number, it's like adding the positive equivalent. So, [tex]\(1.9 - (-38.5)\)[/tex] is the same as [tex]\(1.9 + 38.5\)[/tex].

4. Final calculation:
- [tex]\(1.9 + 38.5 = 40.4\)[/tex].

Therefore, the result of [tex]\(13.1 - 20.2 + 9 - (-38.5)\)[/tex] is [tex]\(40.4\)[/tex].
