Description of Equation for Change in Consumer Surplus for Transportation Demand

The equation should read as follows:

Ben subscript Net equals delta C S. This equals C S subscript one minus C S subscript zero. This expression is equal to parenthesis, the integral from zero to q subscript one, p, parenthesis q, closed parenthesis, d q minus p subscript one, multiplied by q subscript one, closed parenthesis. Minus parenthesis, the integral from zero to q subscript zero, p, parenthesis, q, closed parenthesis, d q, minus p subscript zero, multiplied by q subscript zero, closed parenthesis. This is also equal to the interval from q subscript zero to q subscript one, p, parenthesis, q, closed parenthesis, d q, minus p subscript one, multiplied by delta q, plus q subscript zero, multiplied by delta p.
