Hannah's monthly budget is $1,750.
Her monthly costs are...
Insurance - $230
$98 - Utilities
$250 - Taxes
This adds up to $578.
1,750 - 578 = 1,172
The total amount of extra money Hannah has per month after her monthly costs is $1,172.
Any house/apartment that costs $1,172 OR LESS she will be able to afford.
I hope I've helped!
