Answer:

Rental charge is $273.97

Step-by-step explanation:

Given that Kenny rented an SUV for 3 days and drove it 430 miles. The daily rate was $46.99 and $0.35 per mile with the first 50 miles being free. we have to find the rental charge.

Total miles which drove are 430 miles.

Given that first 50 miles are free ∴ the charged miles are 430-50=380 miles

Cost of 1 mile given is $0.35

Cost for 380 miles is $$0.35\times 380=$133$

The daily rate was $46.99 therefore for three days 3($46.99)=$140.97

Hence, the total charge is = Cost for 380 miles + Daily rate for 3 days

= $133+$140.97 =$273.97
