Answer :
Given
the White House announced the purchase of 17,600 new fuel-efficient vehicles for the federal fleet
new fleet, which includes 2,500 hybrid sedans, will cost $265 million.
Find
a) what will be the average cost per non-hybrid vehicle?
b) how many gallons of gasoline and how many pounds of carbon dioxide will be "saved" per year per vehicle
Explanation
a) If each hybrid vehicle will have an average cost of $22,000 .
each hybrid car costs =
[tex]$ 22,000 $\times2500=55,000,000[/tex]total cost of non - hybrid cars = $265,000,000 - $55,000,000 = $210,000,000
Average cost of non hybrid car = $210,000,000/(17,600-2,500) = $13,907.28 per non hybrid car = $13907
b) 1.8 million gallons per year and prevent 27 million pounds of carbon dioxide from entering the atmosphere.
1,800,000 gallons of gasoline saved per year/17,600 = 102.27 = 102 gallons of gasoline saved per car
27,000,000 pounds of carbon dioxide / 17,600 = 1,534.09 = 1534 pounds of carbon dioxide saved per car
Final Answer
Hence , Average cost of non hybrid car is $13907
b) 102 gallons of gasoline saved per car and 1534 pounds of carbon dioxide saved per car
