Range = 147 - 130 = 17
To find the range, we need to determine the difference between the highest and lowest values in the given set of numbers. Let's arrange the weekly welfare payment amounts in ascending order:
$130, $136, $136, $136, $139, $147
The lowest value is $130, and the highest value is $147. To calculate the range, we subtract the lowest value from the highest value:
Range = Highest Value - Lowest Value Range = $147 - $130 Range = $17
Therefore, the range of the weekly welfare payments is $17.
The correct answer is D. $17.
