The function D ( p ) D(p) gives the number of items that will be demanded when the price is p. The production cost, C ( x ) C(x) is the cost of producing x items. To determine the cost of production when the price is $5, you would: A. Solve C(D(p)) = 7 for p
B. Evaluate D(C(7))
C. Evaluate C(D(7))
D. Solve D(C(x)) = 7 for x

Step-by-step explanation:

Given:

D(p): Items demanded when price is P

C(x): Production cost of x items

Required

Cost of producing when price is $5

First, we need to get the number of items demanded;

To do this, we substitute 5 for P in D(p)

This gives;

Next, we determine the production cost;

To do this, we substitute D(5) for x in C(x)

This gives;
