Question

the revenue from selling x shirts is r(x)=12. the cost of buying x shirts is c(x)=5x+20. the profit from selling x shirts is p(x)=r(x) - c(x). what is p(x)?

Answer 1

The profit function would be p(x) = 7x - 20

Explanation:

In order to find this, start by listing just as asked.

p(x) = r(x) - c(x)

Now input the functions where indicated

p(x) = 12x - (5x + 20)

p(x) = 12x - 5x - 20

p(x) = 7x - 20

Answer 2

The value of
`p(x)=-5x-8`

Explanation:

Given : The revenue from selling x shirts is
`r(x)=12`. The cost of buying x shirts is
`c(x)=5x+20`. The profit from selling x shirts is
`p(x)=r(x) - c(x)`.

To find : What is p(x)?

Solution :

The revenue from selling x shirts is
`r(x)=12`.

The cost of buying x shirts is
`c(x)=5x+20`.

The profit from selling x shirts is
`p(x)=r(x) -c(x)`

Substitute the values in the formula,

`p(x)=12 -(5x+20)`

`p(x)=12 -5x-20`

`p(x)=-5x-8`

Therefore, The value of
`p(x)=-5x-8`
