during a thanksgiving weekend, a car rental company rented 6 - tenths of their vehicles, including two - fifths of the 4 wds that it had. if 40 % of the vehicles are 4 wds, then what percent of the vehicles that were not rented were not 4 wds?  Choose the correct answer:	A) 20 %	B) 30 %	C) 40 %	D) 50 %	E) 60 %

during a thanksgiving weekend, a car rental company rented 6 - tenths of their vehicles, including two - fifths of the 4 wds that it had. if 40 % of the vehicles are 4 wds, then what percent of the vehicles that were not rented were not 4 wds?
multiply(divide(divide(multiply(const_2, 40), add(const_3, const_2)), 40), const_100)
4 / 10 of all the vehicles were not rented . ( 3 / 5 ) ( 2 / 5 ) = 6 / 25 of all the vehicles are 4 wds that were not rented . ( 6 / 25 ) / ( 4 / 10 ) = 3 / 5 is the fraction of non - rented vehicles that were 4 wds 1 - 3 / 5 = 40 % of non - rented vehicles were not 4 wds . the answer is c .
