### You have been hired by an unprofitable firm to determine whether or not to shut it down.

There is some data you are given, and on the basis of the data, you are asked to make a decision. Now here are some definitions TR = Total Revenue TC = Total Cost FC = Fixed Costs VC = Variable Costs Now, TC = FC + VC, and Profit = TR - TC = TR - FC - VC. Let us now substitute the data, and TR = \$30 per unit * 300
