35(5) + .1x = 25(5) + .25x .1x = -50 +.25x (solve for x [remove 175 from the left side]) .15x = 50 (flip the signs, save a step) x = at least 333.33 miles   Proof drive 100 miles One car company = 35*5 + .1(100) = $185         Another car rental = 25*5 + .25(100) = $150   drive 400 miles One car company = 35*5 + .1(400) = $215         Another car rental = 25*5 + .25(400) = $225   drive 333.33 One car company = 35*5 + .1(333) = $208.3   ~    Another car rental = 25*5 + .25(333) = $208.25  Can i have brainlest please?
