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*168 \\ =378 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/5cy17y0tqv838ygvhh9y68zg41flhjvu3s.png)
The terms to express the demand for candy and the price is
![d=(378)/(p)](https://img.qammunity.org/2023/formulas/mathematics/college/z866f57re1ofzaclgomqe8cm2isxt2wf0n.png)
b) The number of bags therefore is:
![\begin{gathered} d=(378)/(p) \\ d=(378)/(3) \\ d=126 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/snc3di8udmxm3dfd3g7k1wn9smcyd5fvgu.png)
Final answer:
a) d= 378/p
b) d = 126 bags of candy
