C is 27/40. If you add it to 1/8 and simplify, you get 4/5.
Since your probably solving for W, isolate W by adding the -3n to both sides and get W=5n now use a calculator and multiply 5 and Pi. To Get 15.7.
I used N for pi since I don’t have that symbol
You need to specify what needs to be solved so I just assumed W
The answer would be C because they say if 3 new students arrived each year.
The answer is 523.6 and all you have to do is round it to the nearest hundredth
