Let's break down each scenario to calculate the future value of the deposits.\r
\n" ); document.write( "\n" ); document.write( "a) Annual Deposits of $10,000, 10% Annual Interest\r
\n" ); document.write( "\n" ); document.write( "Payment (PMT): $10,000
\n" ); document.write( "Interest Rate (r): 10% or 0.10
\n" ); document.write( "Number of Years (n): 6
\n" ); document.write( "We'll use the future value of an ordinary annuity formula:\r
\n" ); document.write( "\n" ); document.write( "FV = PMT * [((1 + r)^n - 1) / r]\r
\n" ); document.write( "\n" ); document.write( "FV = $10,000 * [((1 + 0.10)^6 - 1) / 0.10]\r
\n" ); document.write( "\n" ); document.write( "FV = $10,000 * [(1.10^6 - 1) / 0.10]\r
\n" ); document.write( "\n" ); document.write( "FV = $10,000 * [(1.771561 - 1) / 0.10]\r

\n" ); document.write( "\n" ); document.write( "FV = $77,156.10\r
\n" ); document.write( "\n" ); document.write( "b) Semiannual Deposits of $5,000, 10% Annual Interest (5% per Period)\r
\n" ); document.write( "\n" ); document.write( "Payment (PMT): $5,000\r
\n" ); document.write( "\n" ); document.write( "Interest Rate per Period (r): 10% / 2 = 5% or 0.05\r

\n" ); document.write( "\n" ); document.write( "Payment (PMT): $2,500\r
\n" ); document.write( "\n" ); document.write( "Interest Rate per Period (r): 10% / 4 = 2.5% or 0.025\r
