"dora put $144 into an investment that gave her a 12.5% return on her investment. how much money did dora have after the investment?"I wonder if that question was somebody's school homework question...
* If you want to calculate what the 12.5% return was:
[12.5/100 * $144] = $18
* If you want to calculate what the end amount was with $144 invested at 12.5%pa return:
[1.125*$144] = $162
Oh well, if that was somebody's school homework then I've just answered that question for them...
Edit 04/05/12 : It was definitely somebody's school homework question... Broward County Public School in Miami Florida to be precise... got more googlers from Staten Island in NYC so maybe it was in some sort of national exam or something lol
