9-94.

At the Keaveny Hardware Manufacturing Company they need to meet very specific criteria for the diameter of the threads of #$10$ wood screws. The diameter of the threads must be $\frac { 3 } { 16 }$ of an inch. The width cannot vary more than $\frac { 1 } { 64 }$ of an inch from the specified diameter. Write and solve an appropriate absolute value inequality for this situation. Graph your solution.

Review Section 9.1.3 on absolute value equations and inequalities, specifically problem 9-29.

$|x-\frac{3}{16}|\le\frac{1}{64}$
$\frac{11}{64} \le x \le \frac{13}{64} \text{ inches}$

Use the eTool below to graph the inequalitiy.
