According to the graph, how much did individuals making $20,000 to $50,000 a year pay in income taxes? according to the graph, how much revenue did the government receive from individuals earning $200,000 and above?

$450

Explanation:  Net operating income is the income a company has left with after deducting for fixed and variable expenses. It is also denoted as EBIT, Earnings before interest and tax.

EBIT = sales - ( variable expenses + fixed expenses )

now,

sales = $40 * (1000 + 50 )units = $42000

variable expense = ($30 + $1)*(1050 units) = $32,550

fixed expenses = $7000 + $2000 = $9000

therefore,

EBIT =  $42000 - ($32,550 +  $9000) = $450
