For a certain experiment, a student requires 100 milliliters of a solution that is $8 \%$ HCl (hydrochloric acid). The storeroom has only solutions that are $5 \% \mathrm{HCl}$ and $15 \%$ HCl. How many milliliters of each available solution should be mixed to get 100 milliliters of $8 \% \mathrm{HCl} ?$
