question 8
the function ( d(p) ) gives the number of items that will be demanded when the price is ( p ).
the production cost, ( c(x) ), is the cost of producing ( x ) items.
to determine the cost of production when the price is $6, you would:

• solve ( c(d(p)) = 6 )
• solve ( d(c(x)) = 6 )
• evaluate ( c(d(6)) )
• evaluate ( d(c(6)) )

question help: video message instructor

Explanation:

Step1: Find demand at price $6$

\(D(6)\) gives quantity demanded when \(p=6\)

Step2: Find cost for that quantity

\(C(D(6))\) calculates cost of \(D(6)\) items

Answer:

Evaluate \(C(D(6))\)
