1. The problem is to find the sum of the numbers: 2,400,000.00, 1,800,000.00, 1,800,000.00, 1,200,000.00, 1,200,000.00, and 900,000.00. 2. The formula for the sum of a list of numbers is: $$\text{Sum} = a_1 + a_2 + a_3 + \cdots + a_n$$ where $a_i$ are the numbers in the list. 3. Substitute the given numbers into the formula: $$\text{Sum} = 2,400,000 + 1,800,000 + 1,800,000 + 1,200,000 + 1,200,000 + 900,000$$ 4. Add the numbers step-by-step: $$2,400,000 + 1,800,000 = 4,200,000$$ $$4,200,000 + 1,800,000 = 6,000,000$$ $$6,000,000 + 1,200,000 = 7,200,000$$ $$7,200,000 + 1,200,000 = 8,400,000$$ $$8,400,000 + 900,000 = 9,300,000$$ 5. Therefore, the sum of the numbers is: $$\boxed{9,300,000}$$
