Bill is laying power cable for a new neighborhood. There are going to be 18 east-west streets that are 2 miles long and 10 north-south streets that are four miles long. It takes 5 miles of cable to electrify 1 mile of street. If cable costs $2000/mile, what is the total cost of cable for the neighborhood?
First find the total distance of the east-west streets: 18 streets * 2 miles/street =

<output>36</output>
36 miles.
Then find the total distance of the north-south streets: 10 streets * 4 miles/street = 
<gadget id="calculator">10*4</gadget>
<output>40</output>
40 miles.
Then add the number of miles from each type of street to find the total distance: 36 miles + 40 miles = 
<gadget id="calculator">36+40</gadget>
<output>76</output>
76 miles.
Then multiply that number by 5 to find the number of miles of cable needed: 76 miles street * 5 miles cable/mile street = 
<gadget id="calculator">76*5</gadget>
<output>380</output>
380 miles of cable.
Then multiply that number by the cost of one mile of cable to find the total cost: 380 miles * $2000/mile = $

<output>760_000</output>
760,000.
