Now we will solve for y using what we got for x.

Solution:
A: 
Answer: 150 <= x < 250
Step-by-step explanation:
A number, x, rounded to 1 significant figure is 200
Write down the error interval for x
Rounding x to 1 significant figure means that all subsequent digits after the first is rounded down to zero(0) (if the immediate number after the first is digit 5 or more, it is rounded to 1 and added to the first digit).
The answer would be rotation
