Final answer:
Saabira's disposable income is $49,300, which is her annual salary of $58,000 minus the total tax paid at a 15% tax rate ($8,700).
Step-by-step explanation:
Saabira's disposable income is calculated by subtracting the total tax she pays from her annual salary. If Saabira earns $58,000 a year and pays a 15% average annual tax rate, her total tax paid would be $58,000 multiplied by 15%, which equals $8,700. Therefore, her disposable income would be her annual salary minus the total tax paid, which is $58,000 - $8,700 = $49,300.
To calculate Saabira's disposable income, we first need to calculate the amount of taxes she pays. We can do this by multiplying her annual income by her average annual tax rate. So, 15% of $58,000 is 0.15 x $58,000 = $8,700.
To calculate Saabira's disposable income, we subtract the amount of taxes she pays from her annual income. So, her disposable income is $58,000 - $8,700 = $49,300.
