You can put this solution on YOUR website!
I'll say the purchase price is \"p\"
\n" ); document.write( "Installment plan:
\n" ); document.write( "25% down leaves \".75p\" left to pay off in 3 years
\n" ); document.write( "Entire bill plan:
\n" ); document.write( "\"p+-+.1p+=+.9p\" You pay 90% of the bill immediately
\n" ); document.write( "---------------------
\n" ); document.write( "The 2nd plan puts \".1p\" in your pocket immediately
\n" ); document.write( "With the 1st plan, you can invest \".75p\" at 5% the 1st
\n" ); document.write( "year, which is \".05%2A.75+=+.0375p\"
\n" ); document.write( "The 2nd year, you have \".5p\" to invest at 5%, which is
\n" ); document.write( "\".05%2A.5p+=+.025p\"
\n" ); document.write( "The 3rd year, you have \".25p\" to invest at 5%, which is
\n" ); document.write( "\".05%2A.25p+=+.0125p\"
\n" ); document.write( "Adding these for the 3 years, I get \".0375p+%2B+.025p+%2B+.0125p+=+.075p\"
\n" ); document.write( "This looks like the 2nd plan wins, since
\n" ); document.write( "\".1p\" is greater than \".075p\"
\n" ); document.write( "
\n" );
