Final answer:
The total loss from the break-in is $34,600.
Step-by-step explanation:
The subject of this question is Mathematics, as it involves calculations related to the value of stolen goods and the cost of the security system. To determine the total loss, we need to calculate the sum of the cash, the cost of the televisions, and the decrease in value of the security system.
The total loss can be calculated as follows:
Total Loss = Cash + Cost of Televisions + Decrease in Value of Security System
= $9,000 + $17,500 + ($10,800 - $2,700)
= $9,000 + $17,500 + $8,100
= $34,600
Therefore, the total loss from the break-in is $34,600.
