Question

The revenue, in dollars, of a company that makes toy cars can be modeled by the polynomial 3x2 + 4x – 60. The cost, in dollars, of producing the toy cars can be modeled by 3x2 – x + 200. The number of toy cars sold is represented by x.

If the profit is the difference between the revenue and the cost, what expression represents the profit?

3x – 260
3x + 140
5x – 260
5x + 140

Answer 1

5x – 260

i hope this helps you

Answer 2

For this case we have the following quadratic functions:

Revenue:
`image`

Cost:
`image`

Then, we observe that the profit is given by the following mathematical relationship:

`image`

Substituting values we have:

`image`

Making the corresponding calculations we have:

`image`

Answer:

An expression that represents the profit is:

`Profit = 5x - 260`
