SOLUTION: abs(x-0.004)< or equal to 0.003 Which could be represented by this inequality 1) The thickness of a cylindrical copper wire should exceed 0.044 inch by at least 0.003 inch

Question 1020962: abs(x-0.004)< or equal to 0.003
Which could be represented by this inequality
1) The thickness of a cylindrical copper wire should exceed 0.044 inch by at least 0.003 inch
2)The index of refraction of a glass lens should be above or below 0.044 by at least 0.003

I think you have typos (as in more the one).
As posted, the answer is neither 1) nor 2)

"The thickness of a cylindrical copper wire should exceed 0.044 inch by at least 0.003 inch" (with = thickness in inches) translates as
<--> .

"The index of refraction of a glass lens should be above or below 0.044 by at least 0.003" (with = index of refraction) translates as
<--> .

The answer could be
3) The index of refraction of a glass lens (or thickness of a cylindrical copper wire in inches) should be above or below 0.004 by no more than 0.003 ,
or
4) The index of refraction of a glass lens (or thickness of a cylindrical copper wire in inches) should be within 0.003 of 0.004.
