h represents the number of hours
<h3>Find</h3>
Which of the descriptions is true.
<h3>Solution</h3>

- For h=20, KKP is cheaper (YES—EHP charges $460; KKP charges $455)

Answer:</h2>
Tax= $ 7,173.5
<h2>Step-by-step explanation:
</h2>
Her taxable income is $ 43,000 which lies in the tax category $ 31,850 to
$ 77,100.
Tax for $ 31,850 is $ 4,386
Plus 25% of the amount = ( $ 43,000- $ 31,850 )= $ 11,150 over
25 % of $ 11,150= $ 2,787.5
Total Tax= $ 4386 + $ 2787.5= $ 7,173.5
