Algebra.Com's Answer #698651 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! 4500* ((1+(.052/12)^(36)) + 200(1+.052)^36-1)/(0.052/12). The 200 goes into a separate term. Essentially, what you are doing is figuring the ongoing value of the original $4500 and then adding to it the amount you are contributing each month as well. The 4500 is the compound interest formula, and that is just added to the periodic deposit formula. \n" ); document.write( " \n" ); document.write( " |
