Consumer Mathematics Carlos Sontera is replacing an expensive barbed-wire fence on a ranch in El Paso, Texas. The barbed wire and poles for 12 feet of fence cost about $80. The labor cost to install 12 feet of fence is about $40. A ranch hand reports that 300 new feet of fence are needed. However, when Carlos actually rides out there and measures it, he finds that only 228 new feet of fence are needed. What is the difference in cost of the ranch hand’s estimate versus Carlos’s estimate of how many feet of fence are needed?
