So if 2,000 is the same as 4/15 in Bryce Canyon, then you need to find 15/15 to get the total. You can do this by first dividing 2000 by 4 to get 500, which is equal to 1/15 of Bryce Canyon. Now, if you multiply 500 by 15, you will get 15/15 which equals 7,500 stars, which is answer J. I hope this helps!
