Suppose that next year the U.S. will be in one of the following economic conditions: Boom, Moderate Growth, Recession, or Depression. The probability that each economic condition will occur, and that a jewelry store will earn profits within that broader economic condition are listed below:

Economic Condition	Probability	Store Profits
Boom	0.4	$ 400,000.00
Moderate Growth	0.3	$ 300,000.00
Recession	0.2	$ 100,000.00
Depression	0.1	$ (500,000.00)

The standard deviation of the jewelry store's profits next year (rounded to the nearest dollar) is?
