a car rental agency charges a fee of 35 per day plus $.20 for each mile driven . how much will it cost to rent the car for 6 days and driven 800 miles?

35*6 + 0.20*800 = $370.00

To calculate the cost of renting a car for 6 days and driving 800 miles, we will need to calculate the total cost for both the daily fee and the mileage fee.

First, let's calculate the daily fee for renting the car for 6 days. The agency charges $35 per day, so the total cost for 6 days can be found by multiplying the daily fee by the number of days:
6 days x $35/day = $210

Next, let's calculate the mileage fee. The agency charges $0.20 for each mile driven, and you drove 800 miles. So, the mileage fee can be calculated by multiplying the number of miles driven by the cost per mile:
800 miles x $0.20/mile = $160

Finally, to find the total cost, we need to add the daily fee and the mileage fee:
Total cost = Daily fee + Mileage fee
Total cost = $210 + $160
Total cost = $370

Therefore, it will cost $370 to rent the car for 6 days and drive 800 miles.
