Final answer:
Belvedere spent $310 on bracelets and drones. He returned $135 worth of bracelets and found $20. The total change to Belvedere's funds is $155.
Step-by-step explanation:
To calculate the total change to Belvedere's funds, we need to calculate the total amount spent and the total amount returned or found. Let's start with the amount spent:
Belvedere bought 6 bracelets for $45 each, so the total spent on bracelets is 6 * $45 = $270.
Belvedere also bought 4 drones for $10 each, so the total spent on drones is 4 * $10 = $40.
The total spent on bracelets and drones is $270 + $40 = $310.
Now let's calculate the total amount returned or found:
Belvedere returned 3 bracelets, so the total returned is 3 * $45 = $135.
Belvedere found 2 ten-dollar bills, so the total found is 2 * $10 = $20.
The total amount returned or found is $135 + $20 = $155.
To find the total change to Belvedere's funds, we need to subtract the total amount spent from the total amount returned or found:
Total change = ($310 - $155) = $155.
Therefore, the total change to Belvedere's funds is $155.
