Final answer:
The accurate equation for the profit function based on the number of frisbees sold is P(f) = 5f - 200.
Step-by-step explanation:
The profit function, denoted as 'P', represents the profit made after selling a specific number of frisbees. To find the correct equation for the profit function, we need to consider the cost of purchasing the frisbees and the revenue generated from selling them. In this case, the cost of purchasing 175 frisbees is $200, and the revenue generated from selling each frisbee for $5 is 5f, where f is the number of frisbees sold. Thus, the accurate equation for the profit function is P(f) = 5f - 200.
