The state income tax where Kristin lives is levied at the rate of $p\%$ of the first
$\textdollar 28000$ of annual income plus $(p + 2)\%$ of any amount above $\textdollar 28000$. Kristin
noticed that the state income tax she paid amounted to $(p + 0.25)\%$ of her
annual income. What was her annual income? 
$\textbf{(A)}\,\textdollar 28000 \qquad \textbf{(B)}\,\textdollar 32000 \qquad \textbf{(C)}\,\textdollar 35000 \qquad \textbf{(D)}\,\textdollar 42000 \qquad \textbf{(E)}\,\textdollar 56000$
Let the income amount be denoted by $A$.
We know that $\frac{A(p+.25)}{100}=\frac{28000p}{100}+\frac{(p+2)(A-28000)}{100}$.
We can now try to solve for $A$:
$(p+.25)A=28000p+Ap+2A-28000p-56000$
$.25A=2A-56000$
$A=32000$
So the answer is $\boxed{\textbf{(B) }\textdollar 32000}$.
