I did both at my standard rate of 1 dollar per 100 words. 1 article was 500 and the other was 700, although I specialiaze in longer ones like 1-2k. I believe I charged 12 dollars for both combined.
While I believe you are a US citizen in college, I don't think English is a strong language for you.
You've made so many grammar mistakes. Isn't US supposed to be capitalized? Isn't 1 supposed to be written as one? You misspell specialize, you don't capitalize K (as in thousand). Upto is two separate words.
These are all from your posts. I didn't look through your examples.
Your rates are premium for someone who can't do a premium job.
