a cellular phone company offers a contract for which the cost C, in dollars, of t minutes of telephoning is given by c = 0.25(t-300) + 53.95, where it is assumed the t is >= or equal to 300 minutes. What times will keep cost between $93.20 and $127.20?
\n" ); document.write( "For the cost to be between $93.20 and $127.20, the telehoning time must be between _____ minutes and _____ minutes.\r
\n" ); document.write( "\n" ); document.write( "----------------------------------------------
\n" ); document.write( "93.20 <= 0.25(t-300) + 53.95 <= 127.20
\n" ); document.write( "Solve the inequality for \"t\":
\n" ); document.write( "1st: subtract 53.95 all along the line of the inequality.
\n" ); document.write( "2nd: divide by 0.25 all along the line
\n" ); document.write( "3rd: add 300 all along the line to see the solution.
\n" ); document.write( "==============================
