so the question is
:
5% of total sale is 125

'of' means mutiply
'is' means equals

percent means parts out of 100
5%=5/100=1/20
so now we have
1/20 times total sale=125
multiply both sides by 20 to clear fraction
20/20 times total sale=2500
1 times total sale=2500
total sale=2500
answer is total sale=$2500
