A new surgical facility called Cut & Sew is opening in neighborhoods throughout the United States. They are job shops that handle a variety of outpatient surgical procedures.

\text { Patent } & \text { Cut Time hours) } & \text { Sew Time hours) } \
\text { A } & 2.3 & 2.8 \
\text { B } & 2.5 & 3.0 \
\text { C } & 2.0 & 1.5 \
\text { D } & 0.6 & 1.0 \
\text { E } & 3.6 & 2.6
\end{array}$$
