Rainbow Paints is discontinuing a line of paint that it purchased at $$44$ less $25\%$ and $12\%$ per $4$ L pail. The store's overhead is $50\%$ of cost$,$ and normal operating profit is $25\%$ of cost$.$ If the manager of the store is prepared to accept a loss of one$-$quarter of the overhead expenses, what markdown rate can the store offer in order to clear out the paint? $($Do not round intermediate calculations and round your final answer to $1$ decimal place.$)$
