D. Practical Applications

Welding A piece of metal must be cut to a length of $22\frac{3}{8}\text{ in}\text{. }\pm \frac{1}{16}\text{ in}\text{.}$ What are the longest and shortest acceptable lengths? (Hint: The symbol ± means to add $\frac{1}{16}\text{ in}\text{.}$ to get the longest length and subtract $\frac{1}{16}\text{ in}\text{.}$ to get the shortest length. Longest $=22\frac{3}{8}\text{ in}\text{. }+\frac{1}{16}\text{ in}\text{.}$; Shortest $=22\frac{3}{8}\text{ in}\text{. }-\frac{1}{16}\text{ in}\text{.}$)
