Final answer:
The value of the company's output included in the 2010 GDP is $600.
Step-by-step explanation:
The value of the company's output that will be included in the 2010 GDP can be calculated by multiplying the number of units sold in 2010 by the market value per unit. In this case, the company sold 6 dishwasher machines in 2010 and the market value per unit was $100, so the value of their output included in the 2010 GDP is:
6 units x $100 per unit = $600
