How much do you owe?
Since each roommate will pay 20% of the $6,000 bill, you will owe 1 * 0.2 * 6000 = $1200.
What is 10% of the total repair bill?
10% of the total repair bill is 0.1 * 6000 = $600.
What will each roommate's 20% share be?
Each roommate's 20% share will be 0.2 * 6000 = $1200.
I hope this helps! Let me know if you have any other questions.
