The likelihood that a child will attend a live musical performance can be modeled by the following equation.

q=0.01(0.0007 x**2+0.4 x +33) text( ) $15<=x<=100$
Here, q is the fraction of children with annual household income x thousand dollars who will attend a live musical performance during the year. Compute the income elasticity E of demand at an income level of $30,000. (Round your answer to two decimal places.)
