You can put this solution on YOUR website!
You can write an equation for this as follows:
\n" ); document.write( " $\"2.10%2B0.43%2B0.32x=5.73\"$
\n" ); document.write( "Where x is the amount of time talking minus one minute.
\n" ); document.write( "-----------
\n" ); document.write( "Solve for x:
\n" ); document.write( " $\"2.53%2B0.32x=5.73\"$
\n" ); document.write( " $\"0.32x=3.20\"$
\n" ); document.write( " $\"x=10\"$
\n" ); document.write( "But remember, you need to add on that first minute to this result to get the total talk time:
\n" ); document.write( "Total Minutes talked = 11
