Final answer:
The alternative minimum taxable income (AMTI) for Betty is $42,900.
Step-by-step explanation:
The alternative minimum taxable income (AMTI) is calculated by starting with Betty's regular taxable income, which is $35,000. Then, we add back specific deductions that were disallowed under the alternative minimum tax rules:
- Qualified medical expenses: $3,000
- Real estate tax: $1,200
- State income tax: $800
- Charitable contributions: $600
- Mortgage interest on acquisition indebtedness: $2,000
- Home equity interest on a loan used to improve the home: $300
Adding these deductions back to the regular taxable income gives us the alternative minimum taxable income (AMTI). In this case, the AMTI would be:
AMTI = $35,000 + $3,000 + $1,200 + $800 + $600 + $2,000 + $300 = $42,900
