document.write( "Question 1026874: Hello, could someone please help me with a two part problem writing equations? The problem states: Houses in Madison's town are losing 11% of their value each year. Let v be the current value of Madison's house. Write an equation that describes the projected value, p, at a time, t, years from now. I have P=V(1-r)^t and after substituting 11 for r, I got the equation P=V(0.89)^t. Then, the next part states \"Rewrite your equation to find the effective monthly percentage decrease in value\". I thought it might be V=(1-0.11/12)^12t, but I'm not sure. Any help would be appreciated! \n" ); document.write( "

You want to change the equation from viewing as a yearly period to view as a monthly period. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"1-11%2F12\" will give the rate kept for a one-month period.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Next is to make the adjustment for amount of time. t is still YEARS. You know the fact 12 months IS 1 year.
\n" ); document.write( "\"t%2Ayears%2A12%28months%2Fyear%29=12t%2Amonths\", so you seem to ALMOST have the formula correct -----just need the proper grouping symbols for the rendering into \"notation\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"P=V%281-r%2F12%29%5E%2812t%29\"-------------but remember --- t is used in YEARS.
\n" ); document.write( "
\n" );
