==section input If you invested $*[input p=200000], the annual interest is *[input i=2.5]%, and it is kept for *[input t=10] years, find the amount that you will have. ==section solution First, $i% is equal to *[assign i1=$i/100] $i1 in decimal. So the total money is {{{$p*(1+$i1)^$t}}}, which is equal to *[assign i2=$i1+1] *[assign a=$i2^$t] *[assign ans=$a*$p]{{{$p*$i2^$t=$p*$a=highlight(highlight_green(highlight($ans)))}}}. ==section output i1,i2,a,ans ==section check
