Environmentally conscious Susan has been told that a new electric car will only generate 5 ounces of greenhouse gases (GHG) per mile, but that a standard internal combustion car is double that at 10 ounces per mile. However, the nature of electric cars is such that the new technology and electric batteries generate 21,000 lbs. of GHG to manufacture and another 5,000 lbs. to recycle. A standard car generates only 11,000 lbs. of GHG to manufacture, and recycling with established technology is only 800 lbs. Susan is interested in taking a systems approach that considers the life-cycle impact of her decision. How many miles must she drive the electric car for it to be the preferable decision in terms of reducing greenhouse gases? Susan must drive the electric car ay least miles for it to be the preferable decision in terms of reducing greenhouse gases. (Round your response to the nearest whole number.)
