Comment from student : It's S = 200 + 50x - 22
My response : What you write in your response/comment is very unnatural to be true. I do not believe in it.
Hello, is my understanding correct that you are not able to re-write properly from the text ?
Or you obtained your problem via the phone ?
Also, check your keyboard, if it works properly.
Also, check your glasses (if you wear them).
May be, there is a spot on a glass which obscures your vision.
