Let's break down this problem to find the present worth of the annuity.\r
\n" ); document.write( "\n" ); document.write( "**Understanding the Annuity:**\r
\n" ); document.write( "\n" ); document.write( "* **Annuity Amount (PMT):** P250
\n" ); document.write( "* **Start Time:** End of the third year
\n" ); document.write( "* **End Time:** End of the fourth year
\n" ); document.write( "* **Annual Interest Rate (r):** 5% or 0.05\r
\n" ); document.write( "\n" ); document.write( "**Cash Flow Diagram:**\r
\n" ); document.write( "\n" ); document.write( "```
\n" ); document.write( "Time (Years): 0 1 2 3 4
\n" ); document.write( "Cash Flow: 0 0 0 250 250
\n" ); document.write( "```\r
\n" ); document.write( "\n" ); document.write( "**Calculations:**\r
\n" ); document.write( "\n" ); document.write( "1. **Present Value at the End of Year 2:**\r
\n" ); document.write( "\n" ); document.write( " * We need to calculate the present value of the annuity payments at the end of the second year (one year before the first payment).
\n" ); document.write( " * This is a simple two-payment annuity.
\n" ); document.write( " * Use the present value of an ordinary annuity formula:
\n" ); document.write( " * PV = PMT * [(1 - (1 + r)^-n) / r]
\n" ); document.write( " * PV = 250 * [(1 - (1.05)^-2) / 0.05]
\n" ); document.write( " * PV = 250 * [(1 - 0.907029478) / 0.05]
\n" ); document.write( " * PV = 250 * [0.092970522 / 0.05]
\n" ); document.write( " * PV = 250 * 1.85941044
\n" ); document.write( " * PV ≈ 464.85261
\n" ); document.write( " * This means that at the end of year 2, the payments are worth about P464.85\r
\n" ); document.write( "\n" ); document.write( "2. **Present Value at Time 0 (Now):**\r
\n" ); document.write( "\n" ); document.write( " * Now, we need to discount the present value at the end of year 2 back to the present (time 0).
\n" ); document.write( " * PV(at t=0) = PV(at t=2) / (1 + r)^2
\n" ); document.write( " * PV(at t=0) = 464.85261 / (1.05)^2
\n" ); document.write( " * PV(at t=0) = 464.85261 / 1.1025
\n" ); document.write( " * PV(at t=0) ≈ 421.63502\r
\n" ); document.write( "\n" ); document.write( "**Therefore, the present worth of the P250 annuity is approximately P421.64.**
\n" ); document.write( "
