On a certain transatlantic crossing, 20 percent of a ship's passengers held round-trip tickets and also took their cars abroad the ship. If 40 percent of the passengers with round-trip tickets did not take their cars abroad the ship, what percent of the ship's passengers held round-trip tickets?	Pick one:  A) 33.3%  B) 40%  C) 50%  D) 60%  E) 66.6%
0.20P = RT + C   0.4(RT) = no C   =&gt; 0.60(RT) had C   0.20P = 0.60(RT)   RT/P = 1/3=33%   33.3%nswer - 33.3%
