Answer :

[tex]15\%-\$375\ \ \ \ |divide\ by\ 3\\\\\boxed{5\%-\$125}[/tex]
percentages are values given by a fraction of 100
15 % of the value is equivalent to $375
then 100 % of the value is equivalent to - [tex] \frac{375*15}{100} [/tex]
therefore whole amount is = $ 2500
now we have to find how much of this value is 5%
5% of 2500 = [tex] \frac{5}{100} * 2500 = 125 [/tex]
therefore 5% of 2500 is $125
correct answer is $125
