Answer:To find the cost of a typical Tolleson electric bill, we need to calculate what portion of the total average utility cost is for electricity. If the average electric bill is 38% of the total amount, we can multiply the total average utility cost in Tolleson by 0.38:
$192.40 * 0.38 = $72.90
So the cost of a typical Tolleson electric bill is $72.90.
To compare Tolleson's electric bill cost with the national average, we can subtract the national average from Tolleson's average:
$236.24 - $72.90 = $163.34
So the national average is $163.34 higher than Tolleson's average electric bill cost.
Therefore, Tolleson's average electric bill cost is lower than the national average by $163.34.
