Let's work through the problem of finding the combination of these numbers that equals $72,765.

Here are the provided numbers:

• $5,550
• $21,500
• $5,950
• $7,700
• $450
• $6,990
• $7,675
• $11,600
• $13,135
• $5,800
• $7,000
• $11,100

I will find which subset of these numbers adds up to $72,765. Let's calculate that.The combination of numbers that adds up to $72,765 is:

• $5,550
• $21,500
• $5,950
• $7,700
• $6,990
• $7,675
• $11,600
• $5,800
