Let us suppose that Miss Santos had money amounting to 2x pesos.
\n" ); document.write( "So she invested x pesos at 1% and x pesos at 8% simple interest per annum.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Interest on x pesos for 1 yr at 1% simple interest per annum = \"x%2A1%2F100+=+x%2F100\" pesos.
\n" ); document.write( "Amount at 1% rate = Principal + Interest = \"x+%2B+x%2F100+=+109x%2F100\" pesos.
\n" ); document.write( "Interest on x pesos for 1 yr at 8% simple interest per annum = \"x%2A8%2F100+=+2x%2F25\" pesos.
\n" ); document.write( "Amount at 8% rate = Principal + Interest = \"x+%2B+2x%2F25+=+27x%2F25\" pesos.
\n" ); document.write( "Total annual income from the interests = \"109x%2F100+%2B+27x%2F25+=+217x%2F100\" pesos.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This amount is equal to 7500 pesos.
\n" ); document.write( "So \"217x%2F100+=+7500\"
\n" ); document.write( "or \"x+=+750000%2F217+=+3456.22\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So Ms. Santos invested 3456.22 pesos at each rate.
\n" ); document.write( "
\n" );
