# How many years will it take for 3000 dollars to double at 2 percent?

This sounds like my core 2 mathematics from last year, it sounds like a geometric progression. your talking about interest, yes? 3000x1.02^n = 6000 6000/3000 = 2 1.02…^n = 2 log (base 1.02) 2 = n n= 35? I'm not quite sure if that's right. Another reply: The exact answer is log(2) / log(1.02) (logarithm in any base, same base for both). Almost exactly 35 years. (1.02 is 1 + 2%). For a quick estimate, divide 70% by the interest rate, in this case, 2% - this gives you 35 years. This is a rough formula, that will fail for higher percentages.

# If the growth rate is 7 percent how many years will it take for the GDP to double?

After n years of 7 percent growth, the value is (1.07) n times the starting value. The answer to the question is the smallest value of n such that (1.07) n >=2 or nlog(1.0…7)>= log(2) or n >= log(2)/log(1.07) = 10.2 So the GDP will double during the 11 th year.
