Question 1208191
.
MANUFACTURING A hardware store sells bags of rock salt that are labeled as weighing 35 pounds. 
The equipment used to package the salt produces bags with a weight that is within 8 ounces of the label weight.
 

Write an absolute value equation to determine the maximum and minimum weights 
for the bag of rock salt. Let x represent the weight of the bag, in pounds.
~~~~~~~~~~~~~~~~~~~~~~~~~



        The question in the problem is posed  INCORRECTLY.


        The correct question should ask about an absolute value  INEQUALITY - - - not about an absolute value equation.



<pre>
8 ounces = 0.5 of a pound.


An absolute value inequality for this problem is

    |x - 35| <= 0.5.    


It is the  <U>ANSWER</U>  to the first question</U>. 



This absolute value inequality is equivalent to this compounded inequality

    -0.5 <= x - 35 <= 0.5


Add 35 to all three terms of the inequality and get the solution

    34.5 <= x <= 35.5.


34.5 pounds and 35.5 pounds are the minimum and the maximum of the weight in a bag.


It is the  <U>ANSWER</U>  to the second question</U>. 
</pre>

Solved completely.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This my solution is a standard mathematical mantra 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;to pronounce when solving such problems.
