To find out which numbers add up to 2819.11, I’ll start by adding the numbers you provided and see if any combination totals 2819.11.

Here are the numbers:

• 101 (x4) = 101 + 101 + 101 + 101 = 404
• 116 (x2) = 116 + 116 = 232
• 104.03
• 119.48
• 164.80 (x6) = 164.80 + 164.80 + 164.80 + 164.80 + 164.80 + 164.80 = 988.80
• 149.35
• 160
• 145 (x12) = 145 * 12 = 1740
• 164.80 (x2) = 164.80 + 164.80 = 329.60

Now, I will calculate the total sum of all the numbers:

$404 + 232 + 104.03 + 119.48 + 988.80 + 149.35 + 160 + 1740 + 329.60 = 5127.26$

The sum of all the numbers is 5127.26, which is greater than 2819.11. I will now try different combinations to find a sum that matches 2819.11.

Let me break down this search.Let's try to find combinations that will sum up to 2819.11. I’ll focus on selecting different groupings and adjusting them. Here's a process where I check smaller combinations:

Trying a potential combination:

• 101 (x4) = 404
• 116 (x2) = 232
• 104.03
• 119.48
• 164.80 (x4) = 659.20
• 149.35
• 160
• 145 (x5) = 725

Let's now add these numbers:

$404 + 232 + 104.03 + 119.48 + 659.20 + 149.35 + 160 + 725 = 2513.26$

This is still below 2819.11, so I need to add a bit more.

Trying to add the remaining values:

If I add:

• Another 164.80
• Another 145

This gives:

$2513.26 + 164.80 + 145 = 2823.06$

This is really close, but slightly over. I’ll adjust further:

Trying another configuration:

• 101 (x4) = 404
• 116 (x2) = 232
• 104.03
• 119.48
• 164.80 (x5) = 824
• 149.35
• 160
• 145 (x6) = 870

$404 + 232 + 104.03 + 119.48 + 824 + 149.35 + 160 + 870 = 2863.21$

It's still slightly over 2819.11. I’ll keep adjusting by removing combinations. Would you like me to keep experimenting with specific combinations, or focus on certain values you want to add?
