The mileage charge for the 500 miles will be 500 * 0.21 = $105.00.  
The insurance charge and other fees will be $46.00.

The total of mileage and insurance is $105.0 + $46.00 = $151.00.

Since your total budget is $200, you will have $200.00 - $151.00 = $49.00 left for the daily rate.  That means you have $49.00/$7.00 = 7 days to complete your travel.
