Use the rules of significant figures to answer the following question: 56.02 - 4.6 + 100.648 a. 153 b. 152 c. 152.068 d. 152.1

It's C.152.068
That's the right answer alright! Not because I copied or anything like that but because if you do 56.02-4.6 on a calculator and then add 100.648 you will get the right answer That's how I got my answer :P 

The answer that makes most sense to me is C. If it’s incorrect please message me and I’ll review the question and figure it out :)

Bis the right answer
