Dear Dr. Anderson,
I hope this email finds you well. I am a student in your Thursday ECON305 class.
I am currently working on Assignment 2 regarding market equilibrium and have a brief question. While reviewing Chapter 4 of the textbook, I had difficulty interpreting the formula on page 82. Specifically, I am unsure whether the tax rate should be applied before or after calculating total revenue.
Could you clarify this point at your convenience, or should I visit your office hours to discuss it further?
Thank you very much for your time and assistance.
Best regards,

Dear Professor Johnson,
I hope you are doing well. I was an active student in your Advanced Linguistics course during the Spring 2026 semester, where I completed my final research project on bilingual acquisition.
I am currently preparing my applications for Master’s programs in Applied Linguistics for Fall 2026. Because your coursework deeply inspired my research focus, I am writing to ask if you would feel comfortable writing a strong letter of recommendation on my behalf.
The first application deadline is December 15th, 2026. To assist you in your decision, I have attached my updated CV, transcript, and personal statement draft. I completely understand if your current commitments do not allow you to take this on.
Thank you very much for your time, support, and mentorship.
