The answer is 89.050 becuase

84.7128

+ 4.337

---------------

89.0498

The rule of adding for sig figs is that since 4.337 has 3 digits after the decimal point, the sum has to have 3 digits after the decimal point also.

So, we can disregard the last 8 and we get 89.049. Now, we round it and since 8>5, and 9>5, the final answer is 89.050.

Here's a good video that really helps: https://www.youtube.com/watch?v=l2yuDvwYq5g

(Please watch it! It's really really helpful! You should start the video at **13:00** because that's where it talks about addition)

I hope this helped you, guest!
