Considering the situation described above, the maximum amount Louise may receive for the retirement savings contributions credit (Saver's Credit) is "$150."
This is because according to the Internal Revenue Service regulations, for individuals filing under the head of household filing status, with an adjusted gross income of $31,876 - $48,750, such person would only be able to receive 10% of his retirement savings contributions credit (Saver's Credit).
Therefore, Louise has only contributed $1,500 to her employer's 401(k) plan. Consequently, she can only receive 10%, which is "$150."
Hence, in this case, it is concluded that the correct answer is "$150."
