In February Wilson’s earnings were 40 percent of his family’s total income. In March Wilson earned 25 percent less than in February. If the rest of his family’s income was the same in both months, then, in March, Wilson’s earnings were approximately what percent Q of his family’s total income?	Choose the correct choice from the following options:
A) 15 %
B) 17 %
C) 24 %
D) 30 %
E) 33 %
