Algebra.Com's Answer #849166 by CPhill(1959)![]() ![]() You can put this solution on YOUR website! Here's how to figure out the monthly deposit you'd need:\r \n" ); document.write( "\n" ); document.write( "**1. Understand the Problem**\r \n" ); document.write( "\n" ); document.write( "This is a future value of an ordinary annuity problem. We need to find the regular payment (monthly deposit) that will result in a specific future value ($50,000) given an interest rate (6%) and a time period (7 years).\r \n" ); document.write( "\n" ); document.write( "**2. Use the Formula**\r \n" ); document.write( "\n" ); document.write( "The future value of an ordinary annuity formula is:\r \n" ); document.write( "\n" ); document.write( "FV = P * [((1 + r)^n - 1) / r]\r \n" ); document.write( "\n" ); document.write( "Where:\r \n" ); document.write( "\n" ); document.write( "* FV = Future Value ($50,000) \n" ); document.write( "* P = Periodic Payment (what we want to find) \n" ); document.write( "* r = Interest rate per period (6% annual rate / 12 months = 0.06/12 = 0.005) \n" ); document.write( "* n = Number of periods (7 years * 12 months = 84)\r \n" ); document.write( "\n" ); document.write( "**3. Solve for P**\r \n" ); document.write( "\n" ); document.write( "We need to rearrange the formula to solve for the periodic payment (P):\r \n" ); document.write( "\n" ); document.write( "P = FV * [r / ((1 + r)^n - 1)]\r \n" ); document.write( "\n" ); document.write( "**4. Plug in the Values and Calculate**\r \n" ); document.write( "\n" ); document.write( "P = $50,000 * [0.005 / ((1 + 0.005)^84 - 1)] \n" ); document.write( "P = $50,000 * [0.005 / (1.517 - 1)] \n" ); document.write( "P = $50,000 * [0.005 / 0.517] \n" ); document.write( "P ≈ $483.37\r \n" ); document.write( "\n" ); document.write( "**Answer:** You would need to deposit approximately $483.37 each month to have $50,000 in the account after 7 years. \n" ); document.write( " \n" ); document.write( " |
