A Prototype fuel-efficient car (P-Car) is estimated to get 85% 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% more 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 option
A) 16 2/3%
B) 35.13 %
C) 50%
D) 60%
E) 66 2/3 %
Assumption   Miles/Gallon   T = 100   P = 185 ( 85% more)   $/gallon   T = 100   P = 120 (20% more)   Miles   100 for both   Cost = (Miles X $/ Gallon)/ M/gallon   T = 100   P = 64.86   Hence 100 - 64.86 =35.13%   Ans 35.13 %
