Final answer:
To make a profit of $100,000 at the new location, the Ontario county would need to process 2,000 prisoners annually.
Step-by-step explanation:
To determine the number of prisoners the Ontario county would have to process annually to make a profit of $100,000 at the new location, we need to consider the costs and revenue associated with processing each prisoner.
The county pays $50,000 per year to lease the facility and estimates it will cost $50 per prisoner to process the paperwork. On the other hand, they receive a $75 commission for each new prisoner they process.
Let's denote the number of prisoners they need to process as 'x'. The total cost to process the prisoners would be $50x (considering a cost of $50 per prisoner). The total revenue from processing the prisoners would be $75x (considering a commission of $75 per prisoner).
To make a profit of $100,000, the total revenue must exceed the total cost by $100,000. Therefore, we can set up the following equation: $75x - $50x = $100,000. Solving this equation, we find that x = 2,000.
Therefore, the Ontario county would need to process 2,000 prisoners annually to make a profit of $100,000 at the new location.
