Answer:
He paid $6,000 in taxes.
Step-by-step explanation:
His final amount after taxes is $24000. In order to obtain this number we had to tax 20% of the total (Note that 100%-20%=80%). In other words if he was taxed 20% he took home 80% of what he was paid. Therefore mathematically we have:

Since we know he was left with $24000 after taxes then:

So originally he had $30,000. So how much did he pay in taxes? We can calculate the difference of both pretax and after tax and we get:
$30,000 - $24,000= $6,000 taxed

Answer:
85
Step-by-step explanation:
<em>The equation for the discriminant is </em>
b^2-4(a)(c)
<em>Plug your numbers in from the equation. </em>
<em>1=a, -7=b, -9=c</em>
<em />
(-7)^2-4(1)(-9)
49-(-36)
49+36
85
