Answer:
C.[tex]p(c)=41.88c[/tex]
Step-by-step explanation:
We are given that
The amount of sales p(c) varies directly with the number of customers(c).
Eight customers bought sweaters of total worth=$335
We have to find the equation that can be used to find the sales for c customers.
According to question
[tex]p(c)\propto c[/tex]
[tex]p(c)=kc[/tex]
Where k=Proportionality constant
Substitute c=8, p(c)=335
Then, we get
[tex]335=8k[/tex]
[tex]k=\frac{335}{8}=41.88[/tex]
Substitute the value of k
Then, we get
[tex]p(c)=41.88c[/tex]
Option C is true.
