Country X taxes each of its citizens an amount equal to 11 percent of the first $40,000 of income, plus 20 percent of all income in excess of $40,000. If a citizen of Country X is taxed a total of $8,000, what is her income? Choose one.
A) $40,000 B) $56,000 C) $64,000 D) $58,000 E) $80,000
Equation is correct, so math must be a problem.   0.11*40,000+0.2*(x-40,000)=8,000 --&gt; 4,400+0.2x-8,000=8,000 --&gt; 0.2x=11,600 --&gt; x=58,000.   Answer: $58,000.
