Answer:
A
Step-by-step explanation:
x=6.28111...
100 x=628.111...
1000x=6281.111...
subtract 
900x=5653
x=5653/900
density of iodine=785×5653/900≈4930.672222...

The student is wrong in not putting a parenthesis between 1/3 and x. An equation of a line has a general equation of y = mx + b where m is the slope and b is the y-intercept. In this case, most likely 1/3 is the slope and 0 is the y-intercept. However, writing the equation like that seems like the x variable is a denominator and if that is the case the equation will not represent a line already.
