To find the combination of numbers that sum to 4,020.57, I'll go through the list of numbers and identify possible combinations.

Given numbers:

• 319.34
• 2,996.93
• 795.64
• 249.00
• 163.10
• 202.54
• 1,963.09
• 1,796.14
• 550.00
• 631.90
• 1,800.00
• 378.88
• 2,002.63
• 1,137.71

I'll calculate this and get the exact combination.It seems I missed a detail in my approach. Let me run the process again to identify the correct combination.It seems there isn't an exact match for the sum of 4,020.57 using the combinations of the given numbers. I'll try a different method to approximate the closest possible sum.The combination of numbers that gives the closest sum to 4,020.57 is:

• 249.00
• 202.54
• 631.90
• 1,800.00
• 1,137.71

This combination sums to 4,021.15, which is very close to the target.

Would you like further details or to explore another combination?

Here are some related questions:

1. What if the sum must be exactly 4,020.57?
2. How do floating-point numbers impact precision in such calculations?
3. How can I automate selecting sums closest to a target?
4. What is the fastest way to compute combinations for large sets of data?
5. Can we exclude some numbers from future calculations?

Tip: When working with floating-point numbers, small differences in sums might occur due to precision limitations.
