calculation question - How many years before X number of sales

Hi, 

I would like to know how to answer the following question, without having to calculate the incremental increase year after year (and without calculator) : 

If A has $6000 of sales today, how many years will it take B to get there, if he has $3000 sales today, with 5% of growth each year ? 

Thanks

You may apply the Rule 72. You divide 72 by the rate and get the number of years to double the initial number:
