Comparing the total costs, Nifty Car Rental is the cheaper option for the Allmans at a cost of $60, while Shazam Car Rental would cost $72.50.
To determine the cheaper rental company for the Allmans, we need to calculate the total cost for each company based on the miles driven. Let's assume the Allmans plan to drive 50 miles.
Nifty Car Rental:
Base fee: $30
Mileage charge: $0.60/mile * 50 miles = $30
Total cost: $30 + $30 = $60
Shazam Car Rental:
Base fee: $55
Mileage charge: $0.35/mile * 50 miles = $17.50
Total cost: $55 + $17.50 = $72.50
