The answer is:  $ 85.81  . _______________________________________________ Explanation: _______________________________________________ (1 gal / 22 mi) * (930 mi) =  (1 gal / 22 mi) * (930 mi / 1) = {the units of "mi" ("miles" cancel out} ; =  (1 gal/ 22) * (930 / 1)  =  (1 gal * 930) ÷ (22 * 1)  ;                                                                             =  (930 gal) ÷ 22 ;                                          =  (465 / 11) gal  =                                                     =  42  3/11 gal = 42.2727272727.... gal . ________________________________________________________       (456 /11)  gal  * ($ 2.03 / gal) =          $85.813636363636363581 ------->  round to:  $85.81 . __________________________________________________________
