A certain galaxy is known to comprise approximately 4 x 10^10 stars. Of every 50 million of these stars, one is larger in mass than our sun. Approximately how many stars in this galaxy are larger than the sun?  Choose the correct choice from the following answers.
A) 800 B) 1,250 C) 8,000 D) 12,000 E) 80,000
Total no. of stars on galaxy = 4 * 10^10   Of every 50 million stars, 1 is larger than sun.   1 million = 10^6 therofore, 50 million = 50 * 10^6   total no. of stars larger than sun = 4 * 10^10 / 50 * 10^6   =40 * 10^2 /5   = 800   therefore answer is 800
