It is hard to see but the first one is 243xy^6/5
Difference means subtraction 14,505-282=14,223ft
Let the no. of stars one can expect to see at Bryce Canyon be x.
Given that : No. of stars visible in the night sky = 2000
Also, given that, it is 4/15 of x.
Now, we have

∴ You can expect to see 7,500 stars at Bryce Canyon.
