1. In the winter, many New England farmers make maple syrup. They tap maple trees for their sap, which is then boiled down to make maple syrup. Farmer Moore is one such New Englander.

Maple sugaring requires three main operations. First, in the late fall or early winter, seasoned wood is cut and split for running the boiler ("evaporator") that boils the sap down into syrup. Then, in mid-winter, maple trees are tapped using a drill ("auger"), and a tap is inserted in the tree. The taps are connected via tubing to a sugarhouse. Finally, when the sap starts to run (usually in late February or early March), it is collected at the sugarhouse, where it is boiled down into maple syrup. Farmer Moore has 1200 worker (labor) hours available during the entire sugaring season, and her workers cut the wood, tap the trees, and run the boiler. Cutting/splitting wood and tapping trees can be done individually, but running the boiler requires two workers (i.e., 2 worker hours = 1 boiling hour).

The table below summarizes the labor requirements, maximum availability of hours for specific steps, and corresponding production rates. Assume all labor costs $18 per hour.
