A telephone switchboard 150 pair cable can be made up with either enameled wire or tinned wire. There will be 600 soldered connections. The cost of soldering a connection on the enameled wire will be P1.75, on the tinned wire, it will be P1.25. A 150-pair cable made up of enameled wire cost P0.60 per lineal foot and those made up to tinned wire cost P0.80 per lineal foot. Determine the length of cable run in ft so that the cost of each installation would be the same.
