1. Uneven Security Deposit calculation

Hello, here is a real life scenario that my roommate and I are trying to determine.

Roommate Z has been at apartment for 8 years and when lease was signed with
new roommate C his (roommate Z's) security deposit was rolled over from
previous lease by landlord.

Roommate Z contributed $400 to security deposit. Roommate C contributed$500 to security deposit.

Total Security deposit $900 Objective: Make sure both roommates pay equal amounts of US Dollars for any damages taken out of security deposit. Roommate Z proposes that Roommate Z gets 44% of left over security deposit and Roommate C gets 56% of security deposit based on the percentage of the total$900 that was contributed.

Roommate C proposes that Roommate C gets $100 off the top of what is returned in the security deposit since he contributed$100 more and then split the remaining amount giving half to roommate Z and half to roommate C.

Which of the above methods ensures that both Roommate Z and Roommate C each pay the same amount toward what is taken out of the security deposits. Please explain your rationale in great detail as neither roommate is great at math. If there is a better way to achieve the above objective please propose that also. Thank you for your time.
