Problem F.1b

[Maggie Doan 1I]

My calculations for the answer were off by the hundredth decimal point. For example I calculated 78.96% when the answer is 78.90%. Would I get the answer wrong?

I think as long as your answer is close enough to the book answer, TAs won't make you wrong. In this case, your answer is very close.

This might be from applying significant figures to the calculations made before arriving at the answer. To have a more precise result, cut off the calculations you make to four decimal places and continue to do so until you arrive at the final answer. Then apply significant figures to the latter.

You may add more decimal places to intermediary calculations as needed if the data given for the problem is especially precise.

Our TA told us that if he was grading (which he is) he would not mark us off. However, he said that if we keep the calculations running in our calculator and round at the very end, our answer should match the answer key.
