The total rental charge in dollars for Trenton's trip for 9 days covering 670 miles will be $639.15.
To compute the total rental charge for the Trenton trip, we calculate the total charges by days and the total charges by miles and then add these together.
For example, the total charges by day are $508.50 ($56.50 x 9), while the total charges by miles are $130.65 (670 x $0.195).
Summing these two charges will give the total charge for the trip.
The number of days for the rental trip = 9 days
Total miles for the trip = 670 miles
Charge per day = $56.50
Charger per mile = $0.195 (19¹/₂ cents)
Total charge = $639.15 {($56.50 x 9) + (670 x $0.195)}
Thus, the total rental charge in dollars for Trenton's trip for 9 days covering 670 miles will be $639.15.
