Answer:
(a). $33075
(b). $30180.20
(c). $29980.20
Step-by-step explanation:
(a). Sticker price = Base price + Options + Destination charge
              = 27520 + 4630 + 925
             = $33075
(b). Dealer's Price = 91.5% of base price + 88% of options + Destination Charge
               = 91.5% of 27520 + 88% of 4630 + 925
               = 25180.80 + 4074.40 + 925
               = $30,180.20
(c). If she pays $200 less on vehicle than dealer's cost then total amount paid by her = 25180.80 + 4074.40 + (925-200)
         = $29980.20
