I am having issues with these two math problems. I have to do the math along with write the math into words pretty much stating how I did this. I am terrible at turning math into words. Can anyone help me with this problem?

1. Airline Revenue. An airline company flies about 25,000 passengers from JFK NY to Canada monthly at the price of $530 per round-trip ticket. Current marketing research predicts that for each $5 increase in ticket price the number of passengers will drop by 150. Find the equation which gives the number of passengers in terms of the ticket price. Find the revenue equation. Find the price for which the revenue is maximized. Create a strong argument against having price set at $729.99. (You might want to make a table and present few values assigning one column to the price of the ticket, then the number of passengers, and finally revenue.)

I have the math done for this but I have no clue on what to write to explain what I did...it needs to be pretty detailed. IF anyone can help please replyy!
