To find the median, we need to arrange the incomes in order from least to greatest:

$30,000 $30,000 $30,000 $30,000 $40,000 $40,000 $40,000 $40,000

The middle two incomes are both $35,000, so the median household income is $35,000.

To find the mean, we need to add up all the incomes and divide by the total number of households:

($30,000 * 4) + ($40,000 * 4) = $280,000 total income 
$280,000 / 8 households = $35,000 mean household income

Therefore, the answer is B.
