(b) Determine the number of bags of candy that will be sold if the price is raised to $3 a bag.Suppose that the demand for candy d is the inversely related to the price p

Answer 1

SOLUTION:

Case: Rates

Method:

a) Since the price of candy is ​$2.25 per​ bag,

The theater sells 168 bags of candy,

Hence:

$\begin{gathered} 2.25\times168 \\ =378 \end{gathered}$

The terms to express the demand for candy and the price is

$d=\frac{378}{p}$

b) The number of bags therefore is:

$\begin{gathered} d=\frac{378}{p} \\ d=\frac{378}{3} \\ d=126 \end{gathered}$

Final answer:

a) d= 378/p

b) d = 126 bags of candy
