The demand function if $p = 60 + 2D - 10D^2$, the rate of charge in price with respect to demand is ______
AnswerClick to flip back
A
$2 - 20D$
💡 Explanation:
The rate of change of price with respect to demand is the derivative dp/dD. Differentiating p = 60 + 2D - 10D² term by term gives dp/dD = 0 + 2 - 20D = 2 - 20D. Option A incorrectly divides 60 by D, and Option C has an incorrect coefficient.
