The cost to rent the truck for 6 hours = 53
Step-by-step explanation:
Rental charges for 3 hours = $17
Additional Charge per 15 mins = $3
Time = 6 hours
6 hours - 3 hours for moving the truck = 3 hours
we need to convert the remainnig 3 hours to minutes
60 minutes = 1 hour
3 hours = 3 × 60 = 180 minutes
We find the number of 15 minutes we can get in 180 minutes:
180/15 = 12
we get 15 mins 12 times
The cost to rent the truck for 6 hours = Rental charges for 3 hours moving the truck + additional charges for every 15 mins × number of times we get 15 mins
The cost to rent the truck for 6 hours = $17 + ($3 × 12)
The cost to rent the truck for 6 hours = 17 + 36
The cost to rent the truck for 6 hours = $53
