Nate Shermach found a two-year-old luxury car advertised for $31,175. Its average retail value is $30,850. It has aluminum alloy
wheels valued at $300 and a theft recovery system valued at $75, but it does not include a CD player, which is valued at $100. The car has been driven 47,005 miles. The used-vehicle guide indicates that if the car’s mileage is between 46,000 and 51,000 miles, $700 should be deducted. What is the average retail price for this vehicle in whole dollars?

= 144
