HELP, PLEASE!

Hello!
I study Industrial Technologies Engineering and I need to do an exercise for the University school. I must invent make up a topic, in order to and then my classmates have to answer the questions I do for ask them about the topic. I need you to review the questions, and say to tell me how I must to write them.
The topic is: You must plan the building of a metro (including finances).  Please plan where should the metro will/should go (you can have more stations
if you think that would be better). Make sure to plan for a returning on investment, and how you can make it keep the project a secret.


1. You must estimate how many people get on the Metro (it depends depending on what time in a of day) in order to calculate how many trains you need, and how many Metro Stations you should build.

2. How much should the ticket cost if you want to recoup the 10 percent of your total investment in the first 3 months? (You need to considerate if you want to determine a prize, or if it whether or not the price is going to depend on how many stations the trip has).

Thank you for your help :)

Regards!

Good job! 

HELP, PLEASE!

Hello!
I study Industrial Technologies (I think is this a direct translation and I think we would use the singular, or Industrial Technology Engineering) Engineering and I need to do an exercise for the University university (capitilization rules). I must invent select (word choice) a topic in order to for (preposition choice) my classmates to answer (infinitive verb) the questions I do write (verb choice) for them about the topic. I need you to review the questions, and say tell (verb choice) to (understood that this is the direct object by position in sentence) me how I must to write them.
The topic is: You must plan a building including finances, where should the metro go (you can have more stations
if you think that would be better), plan for the (word choice) returning on investment, and how you can keep make (word choice) it
secret.


1. You must estimate how many people get on metro Metro (it depends on what time in a day) in order to calculate how many trains you need, and how many metro stations Metro Stations you should build.

2. How much should the ticket cost if you want to recoup the 10 per cent of your total investment in the first 3 months? (You need to considerate if you want to determine a prize [prize is not the right word here.  I think you mean price but this is also a bit confusing. You need to consider if you want the to have a flat fare or based instead on number of stops travelled], or if it is going to depend on how many stations the trip has).

Thank you for your help :)

1) Just one comment.  This text is clear, but there is mostly a problem of word choice, mostly there are phrases that are built differently or questions of connotation in word choice.  Review the capitalization rules.
