conversations.value: I'm stuck on this math problem: 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?
  Can you help?

conversations.value: First find the total distance of the east-west streets: 18 streets * 2 miles/street = 36 miles
  Then find the total distance of the north-south streets: 10 streets * 4 miles/street = 40 miles
  Then add the number of miles from each type of street to find the total distance: 36 miles + 40 miles = 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 = 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 = $760,000
