Let's break this problem into two parts to find the total amount Joe will have in his account.\r
\n" ); document.write( "\n" ); document.write( "**Part 1: First 2 Years of $200 Deposits**\r
\n" ); document.write( "\n" ); document.write( "1. **Monthly Deposit:** $200
\n" ); document.write( "2. **Time Period:** 2 years
\n" ); document.write( "3. **Interest Rate:** 6% per year compounded monthly (0.06 / 12 = 0.005 per month)
\n" ); document.write( "4. **Number of Deposits:** 2 years * 12 months/year = 24 deposits\r
\n" ); document.write( "\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( "Where:\r
\n" ); document.write( "\n" ); document.write( "* FV = Future Value
\n" ); document.write( "* PMT = Periodic Payment ($200)
\n" ); document.write( "* r = Interest Rate per Period (0.005)
\n" ); document.write( "* n = Number of Periods (24)\r
\n" ); document.write( "\n" ); document.write( "FV₁ = 200 * [((1 + 0.005)^24 - 1) / 0.005]
\n" ); document.write( "FV₁ = 200 * [(1.005^24 - 1) / 0.005]
\n" ); document.write( "FV₁ = 200 * [(1.127159776 - 1) / 0.005]
\n" ); document.write( "FV₁ = 200 * [0.127159776 / 0.005]
\n" ); document.write( "FV₁ = 200 * 25.4319552
\n" ); document.write( "FV₁ ≈ $5086.39\r
\n" ); document.write( "\n" ); document.write( "**Part 2: Next 3 Years of $300 Deposits**\r
\n" ); document.write( "\n" ); document.write( "1. **Monthly Deposit:** $300
\n" ); document.write( "2. **Time Period:** 3 years
\n" ); document.write( "3. **Interest Rate:** 6% per year compounded monthly (0.06 / 12 = 0.005 per month)
\n" ); document.write( "4. **Number of Deposits:** 3 years * 12 months/year = 36 deposits\r
\n" ); document.write( "\n" ); document.write( "We'll use the future value of an ordinary annuity formula again, but we also need to account for the FV₁ amount that has been accruing interest for the entire 5 years.\r
\n" ); document.write( "\n" ); document.write( "First calculate the future value of the first 2 years after 5 years.\r
\n" ); document.write( "\n" ); document.write( "FV1_5 = FV1 * (1.005)^36
\n" ); document.write( "FV1_5 = 5086.39 * (1.005)^36
\n" ); document.write( "FV1_5 = 5086.39 * 1.196680526
\n" ); document.write( "FV1_5 = $6086.07\r
\n" ); document.write( "\n" ); document.write( "Then calculate the future value of the next 3 years.\r
\n" ); document.write( "\n" ); document.write( "FV₂ = 300 * [((1 + 0.005)^36 - 1) / 0.005]
\n" ); document.write( "FV₂ = 300 * [(1.005^36 - 1) / 0.005]
\n" ); document.write( "FV₂ = 300 * [(1.196680526 - 1) / 0.005]
\n" ); document.write( "FV₂ = 300 * [0.196680526 / 0.005]
\n" ); document.write( "FV₂ = 300 * 39.3361052
\n" ); document.write( "FV₂ ≈ $11800.83\r
\n" ); document.write( "\n" ); document.write( "**Total Amount in Account:**\r
\n" ); document.write( "\n" ); document.write( "* Total = FV1_5 + FV₂
\n" ); document.write( "* Total = $6086.07 + $11800.83
\n" ); document.write( "* Total = $17886.90\r
\n" ); document.write( "\n" ); document.write( "**Answer:**\r
\n" ); document.write( "\n" ); document.write( "Joe will have approximately $17,886.90 in his account by the end of 5 years.
