Hello, I have a question regarding this problem:

Joyce's office is located in a separate room of the house and occupies 250 square feet. The total square footage of the house is 2,500. The taxpayers purchased the home in 1999, for $70,000, with approximately 20 percent of the purchase price allocated to the land. The total household expenses for the year are as follows:

Heat $2,340

Insurance $1,680

Electricity $760

Repairs to kitchen $2,750

Cleaning $1,740

How do you work out the tax on the property, like the tax on the house. I believe it is $9,400 but how do you get that answer?

How do you also work out home mortgage interest?

Thank you!
