Answer:
His federal income tax is $47,040
Explanation:
In this question, we are asked to calculate the federal income tax paid by Steve if he must pay 28% of his salary and we are given the amount of his salary
To calculate this value, what we simply need to do is to calculate 28% of 168,000
Thus, mathematically we have;
28/100 * 168,000 = 28 * 1680 = $47,040
