proportion
before, she was making 52000
so raise/original=106%/100%=106/100
x=new salary
'how much more'=x-52000
also, since 6% increase, 6% is the how much more
howmuchmore/52000=6%/100%
howmuchmore/52000=6/100
howmuchmore/52000=0.06
multiply both sides by 52000
howmuchmore=3120
she earns $3120 more nex year
