**1. Calculate Quarterly Deposits:**\r
\n" ); document.write( "\n" ); document.write( "* Monthly Savings: R2 480.00
\n" ); document.write( "* Quarterly Savings: R2 480.00/month * 3 months/quarter = R7 440.00\r
\n" ); document.write( "\n" ); document.write( "**2. Calculate the Number of Quarters:**\r
\n" ); document.write( "\n" ); document.write( "* 10 years * 4 quarters/year = 40 quarters\r
\n" ); document.write( "\n" ); document.write( "**3. Calculate the Quarterly Interest Rate:**\r
\n" ); document.write( "\n" ); document.write( "* Annual Interest Rate: 11%
\n" ); document.write( "* Quarterly Interest Rate: 11% / 4 = 2.75%\r
\n" ); document.write( "\n" ); document.write( "**4. Calculate the Future Value of the Annuity**\r
\n" ); document.write( "\n" ); document.write( "* Use the formula for the future value of an ordinary annuity:\r
\n" ); document.write( "\n" ); document.write( " * **FV = P * [(1 + r)^n - 1] / r**
\n" ); document.write( " * where:
\n" ); document.write( " * FV = Future Value
\n" ); document.write( " * P = Quarterly Payment (R7 440.00)
\n" ); document.write( " * r = Quarterly Interest Rate (0.0275)
\n" ); document.write( " * n = Number of Quarters (40)\r
\n" ); document.write( "\n" ); document.write( "* **Calculate:**
\n" ); document.write( " * FV = R7 440.00 * [(1 + 0.0275)^40 - 1] / 0.0275
\n" ); document.write( " * FV = R7 440.00 * [2.9050 - 1] / 0.0275
\n" ); document.write( " * FV = R7 440.00 * 69.2727
\n" ); document.write( " * FV = R514 664.79\r
\n" ); document.write( "\n" ); document.write( "**Therefore, the amount available to Jonathan after ten years in his retirement account is approximately R514 664.79.**
