A Prototype fuel-efficient car (P-Car) is estimated to get 90% 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 60% 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?
Choices
A) 15.78%
B) 33 1/3 %
C) 50%
D) 60%
E) 66 2/3 %
15.78%ssumption   Miles/Gallon   T = 100   P = 190 ( 90% more)   $/gallon   T = 100   P = 160 (60% more)   Miles   100 for both   Cost = (Miles X $/ Gallon)/ M/gallon   T = 100   P = 84.21   Hence 100 - 84.21 =15.78%   15.78%ns 15.78%
