Answer:
$424
Explanation:
The computation of the total tax liability is shown below:
= Unearned income + tax amount
where,
Unearned income is
Since she received an interest income for $5,000 out of which $1,100 is exempt so the remaining amount left is $3,900
Now the first $2,200 would be tax at 10% so it would be $220
And, the rest amount left is
= ($3,900 - $2,200) × 12%
= $204
As this rest amount denotes that it should be taxed at the marginal tax rate
So, the tax liability is
= $220 + $204
= $424
