Question

(93.789 - 5.40) x 18.057 =
answer should be in proper # of SF

My answer is 1596.040173
But my choices are
A)1596,B)1600,C)1596.239,D)1590,E)1596.2

So would the answer be 1590 because of the 3 SF
Thank You!

Answer 1

I think 1600 would be better, since if you round 1596 to 3SF, then you get 1600.

If you don't allow rounding, then 1590 is the way to go.
