Explanation:
Please see attachment.

The plant that offers the lowest total cost is plant A, because it is cheaper than Plant B for all volumes over 8,000,000 units.
Which plant should be chosen?
In order to determine the plant that would be chosen, the total cost of each plant has to be determined.
Total cost = fixed cost + (variable cost x total output)
Total cost of plant A = $4,000,000 + (0.3 x 10 million) = $7million
Total cost of plant B = $3,600,000 + (0.35 X 10 million) = 7.1 million
