To simplify the expression \( 64.35 + 2.8 \):
First, align the numbers for addition:
```
64.35
+ 2.80
```
Now, add them:
1. Starting from the rightmost digit:
- \( 5 + 0 = 5 \)
2. Next column:
- \( 3 + 8 = 11 \) (write down 1 and carry over 1)
3. Next column:
- \( 4 + 2 + 1 = 7 \) (include the carried over 1)
4. Final column:
- \( 6 + 0 = 6 \)
Putting it all together, the sum is:
\[
67.15
\]
Thus, the simplified expression is \( 67.15 \).
The correct choice is:
C. 67.15
