Total rental cost = $390 = 2($30/day) + ($0.25/mile)x     (x=number of miles)
                                                                                          330
Then 390 = 60 + 0.25x     =>    330 = 0.25 x    =>   x = ------------
                                                                                           0.25

x comes out to 1320 miles.
