Algebra.Com's Answer #396239 by 55305(86)![]() ![]() ![]() You can put this solution on YOUR website! Let's assume that Bill's retirement account had $1000 in it right now. So in a year, his account will have 1.08*1000. The next year, he will have 1.08*1.08*1000, and in the next year there will be 1.08*1.08*1.08*1000, or $1259.712. The percent of change formula is something like this: (c-o)/o, with c being the current value, and o being the old value. So we plug in the numbers: ($1259.712-$1000)/1000= $259.712/1000= 0.259712= 25.9712% \n" ); document.write( "So the percent increase is 25.9712%. \n" ); document.write( " |
