Question

A website sells sweaters. The amount of sales p(c) varies directly with the number of customers

Eight customers bought a total of $335 worth of sweaters.
Which equation can be used to find the sales for c customers?

Answer 1

A because that would be the right answer.

Answer 2

C.
`p(c)=41.88c`

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

`p(c)\propto c`

`p(c)=kc`

Where k=Proportionality constant

Substitute c=8, p(c)=335

Then, we get

`335=8k`

`k=(335)/(8)=41.88`

Substitute the value of k

Then, we get

`p(c)=41.88c`

Option C is true.
