(Note that both <math>15</math> and <math>20</math> are greater than <math> 10 </math>, so we can assume <math> \tilde{q}_e > 10 </math> in our calculations.)

• 22:4022:40, 25 March 2025 diff hist +382 N Science:Math Exam Resources/Courses/MATH101 C/April 2024/Question 18 (a)/Solution 1 Created page with "As more of a product is available in the market, it is easier to obtain, so the price per unit that a customer is willing to spend goes down. Therefore, we should expect <math>D(q)</math> to be ''non-increasing'' in <math>q</math>. Thus, the correct answer is G. We know that <math>D(q)=\frac{1}{2^q}+1</math> because that is the only non-increasing function out of the two options."
