I have three questions.
1) Do you understand the assignment in full ?
2) If you do understand it in full, why don't you make it on your own ?
3) If you do not understand some parts of the assignment, which exactly part do you not understand ?
It does not require to invent something.
It only requires to make calculations and to compare your results with the given numbers.
It is not a job for tutors.
Making these simple calculations is YOUR job.
