is the answer B?

Answer 4

When adding, your answer must be rounded to the least number of decimal places present in any term

More specifically, because 6.8 only has 1 decimal place your answer can only have 1 decimal place

Answer 5

Would this mean that the answer is A, and not B, since I am rounding?
