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).
