Question: Suppose that a demand function is linear-that is, q = m - np for 0 p m/n, where m and n are positive

Suppose that a demand function is linear-that is, q = m - np for 0 ≤ p ≤ m/n, where m and n are positive constants. Show that E = 1 at the midpoint of the demand curve on the interval 0 ≤ p ≤ m/n; that is, at p = m/(2n).
