document.write( "Question 820909: You are choosing between two long-distances telephone plans. Plan A has a monthly fee of $25.00 with a charge of $0.10 per minute for all long-distance calls. Plan B has a monthly fee of $6 with a charge of $0.15 per minute for all long-distance calls. Find the cost function (in terms x) for each. For how many minutes of long-distance calls will the costs for the two planes be the same? \n" ); document.write( "
