Step-by-step explanation:
To find the hourly rate, you divide the total cost by the number of hours. The calculation shows that Emilia pays $4 per hour for the boat rental. To calculate how much Emilia pays per hour for the boat rental, you need to divide the total cost by the total hours included in the rental period. The total cost is $24, and she can rent the boat for 6 hours. Therefore, you would calculate it as follows:
Cost per hour = Total cost / Total rental hours
Cost per hour = $24 / 6 hours
Cost per hour = $4 per hour
So, the correct answer to the question is b. $4.
