An outdoor furniture company makes furniture out of recycled plastic.

Their current production strategy calls for four $10-$hour days of

production each week. One step in the process currently use $4$ extruders

which each process at a rate of about $150$ pounds of plastic per hour. This

step also requires $2$ operators who handle loading. clearing, and cleaning

the machines. The company is considering buying an additional extruder

that would work at the same rate $(150lb\frac{s}{h}$our $)$ as the existing extruders.

The company expects the new extruder to be accommodated with no

changes to the labor team. What is the gain in labor productivity in

pounds of plastic per labor$-$hour?
