x = # of posters, y = total cost y = 2x + 250 y = 1000 1000 = 2x + 250 1000 - 250 = 2x 750 = 2x 750/2 = x 375 = x....so 375 posters can be printed ========================== y = total cost, x = # of miles y = 3x + 3 y = 117 117 = 3x + 3 117 - 3 = 3x 114 = 3x 114/3 = x 38 = x.....so the car was towed 38 miles
