Step-by-step explanation:
We can start this problem off by organizing the monthly and the annual expenses.
<u>Monthly:</u>
$725 - Condominium
$125 - Maintenance Work
<u>Annual:</u>
$468 - Insurance
$129 - Lost Interest
$3,000 - Utility Bills
Since we are solving for the average monthly expense, we should deal with the annual expenses first by dividing them all by 12 since there are 12 months.
Now, we simply add 299.75 to the monthly expenses to get our answer.
The average monthly expense is $1,149.75.
