Answer:
Function: Profit(x) = 187.5*x - 4650
Jeffrey's family would need to rent out all 25 kayaks for approximately 33 hours monthly to make a $1500 profit.
Explanation:
To calculate the profit from renting kayaks, we need to subtract the cost of purchasing them from the revenue generated by renting them out.
Let's assume the kayaks are rented out for x hours a month. Then, the profit made in a month would be:
Profit = (25 * $7.50 * x) - (25 * $186) = $187.50x - $4650
To make a $1500 profit, they would need to rent out all 25 kayaks for approximately 33 hours a month.
