The charge to rent a trailer is $20 for up to 2 hours plus $8 per additional hour or portion of an hour. Find the cost to rent a trailer for 3.2 hours, 4 hours, and 7.6 hours.
20 + (2 * 8) = $36
I'll be glad to check your answers for the other two questions.
To find the cost to rent a trailer for a given duration, we can break down the problem into two steps:
Step 1: Calculate the base cost for the first 2 hours.
Step 2: Add the additional cost for each hour or portion of an hour beyond the initial 2 hours.
Step 1: Calculate the base cost for the first 2 hours:
Since the charge for the first 2 hours is a flat rate of $20, the base cost remains the same for any duration up to 2 hours. Therefore, the base cost for any duration less than or equal to 2 hours will be $20.
Step 2: Calculate the additional cost for each hour or portion of an hour beyond the initial 2 hours:
For any duration beyond the initial 2 hours, the charge is $8 per additional hour or portion of an hour. So, if the duration is less than 3 hours, we add $8 for the additional hour.
If the duration is between 3 and 4 hours, we consider it as 4 hours and add $8 since it includes the additional hour.
Now, we can calculate the cost for the given durations:
For 3.2 hours:
Step 1: Base cost for the first 2 hours = $20.
Step 2: Additional cost for 1.2 hours = $8 (since it lies between 1 and 2 hours).
Total cost = Base cost + Additional cost = $20 + $8 = $28.
For 4 hours:
Step 1: Base cost for the first 2 hours = $20.
Step 2: Additional cost for 2 hours = $16 (2 hours beyond the initial 2 hours).
Total cost = Base cost + Additional cost = $20 + $16 = $36.
For 7.6 hours:
Step 1: Base cost for the first 2 hours = $20.
Step 2: Additional cost for 5.6 hours = $48 (5 additional hours beyond the initial 2 hours).
Total cost = Base cost + Additional cost = $20 + $48 = $68.
Therefore, the cost to rent a trailer for 3.2 hours is $28, for 4 hours is $36, and for 7.6 hours is $68.
