Question 1193913
the square footage by apartment is:
apartment 1 = 90
apartment 2 = 90
apartment 3 = 100
apartment 4 = 120
the total monthly expenses are:
water bill = 340
refuse removal bill = 66
sewage bill = 96
annual rates and taxes per year converted to per month = 22300 / 12 = 1858.333333......
annual maintenance converted to monthly = 12000 / 12 = 1000.
the total monthly bill = the sum of all these = 3360.3333.....
apartment 1 share is 90/400 * that = 756.075
apartment 2 share is 90/400 * that = 756.075
apartment 3 share is 100/400 * that = 840.0833333....
apartment 4 share is 120/400 * that = 1008.1
let me know if you have any questions.
