Sure! Let's solve this step-by-step.
1. Identify the income:
The income given in the question is [tex]$30,000.
2. Identify the tax rate:
The tax rate provided is 15%.
3. Convert the tax rate to decimal form:
To make the multiplication easier, convert the percentage to a decimal. This is done by dividing the percentage by 100.
So, 15% becomes 0.15.
4. Calculate the income tax:
To find the income tax, multiply the income by the tax rate in decimal form.
\[
\text{{Income Tax}} = \text{{Income}} \times \text{{Tax Rate}} = 30{,}000 \times 0.15
\]
The result of this calculation is $[/tex]4500.
Therefore, the income tax that must be paid is $4500.
