Mark, Cherry and Eric Jones jointly patented a method for manufacturing Adam Smith bobble head dolls. The plan is for a very limited production run. They investigate the potential market for this unique novelty and find their sales and total cost schedules to be as follows: (The costs include a licensing fee to the estate of Adam Smith)

Sales            Unit Price        Total Cost?
0                      200            140?
1                      180            170?
2                      160            200?
3                      140            220?
4                      120            250?
5                      100            300?
6                        80            380
