Assume that Transylvania discovered that it has 50 x 10^9 bbl of crude oil. it used 3 x 10^6 bbl/d(d=day) last year (as of 12/31/09), and expects yearly usage to double this year and each year in the future. how many years will its supply last? (hint: CRU, logarithms: y = a *x^n => ln a*n x or "trial &error" in excel)
how to use logarithms or trial and error in excel?
