A Prototype fuel-efficient car (P-Car) is estimated to get 80% more miles per gallon of gasoline
than does a traditional fuel-efficient car (T-Car). However, the P-Car requires a special type
of gasoline that costs 20% less per gallon than does the gasoline used by a T-Car. If the two
cars are driven the same distance, what percent less than the money spent on gasoline for the
T-Car is the money spent on gasoline for the P-Car?
Choose the correct choice from the following answers:  A) 16 2/3%  B) 33 1/3 %  C) 50%  D) 55.56%  E) 66 2/3 %
Assumption   Miles/Gallon   T = 100   P = 180 ( 80% more)   $/gallon   T = 100   P = 80 (20% less)   Miles   100 for both   Cost = (Miles X $/ Gallon)/ M/gallon   T = 100   P = 44.44   Hence 100 - 44.44=

<output>55.56</output>
55.56%   Ans 55.56%
<result>D</result>
