2. In the year 2004 (t=0), the world reserves of natural gas were approximately 9671 trillion cubic feet. In that same year, the world consumption of natural gas was approximately 104.1 trillion cubic feet, and was growing exponentially at about 2.6 %per year. If the demand continues to grow at this rate, and no new reserves of natural gas are found, in what year will the world reserves of this resource be depleted?
The world reserves will be depleted in the year (round to nearest year)???
