q=39,8002p²

a. Determine the elasticity ofdemand, E.

E=

(An expression using p as thevariable.)

b. Determine the value of q that maximizes the revenue. Select the correct choicebelow, and ifnecessary, fill in the answer box within your choice.

A. Total revenue is maximized at about q=

(Round to the nearest whole number asneeded.)

B. No values of q maximize total revenue.
