My recent marketing idea, the Miracle Algae Growing Kit, has been remarkably successful, with monthly sales growing by 9% every 6 months over the past 10 years. Assuming that I sold 100 kits the first month, how many kits did I sell in the first month of this year? (Round your answer to the nearest whole number.)
