Tom found a two-year-old luxury car advertised for $31,075. Its average retail value is $30,950. It has aluminum alloy wheels valued at $250 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?

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )
