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

For this case we have the following quadratic functions:

Revenue: [tex] 3x ^ 2 + 4x - 60
[/tex]

Cost: [tex] 3x ^ 2 - x + 200
[/tex]

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

[tex] Profit = Revenue - Cost
[/tex]

Substituting values we have:

[tex] Profit = (3x ^ 2 + 4x - 60) - (3x ^ 2 - x + 200)
[/tex]

Making the corresponding calculations we have:

[tex] Profit = x ^ 2 (3-3) + x (4 + 1) + (-60-200)

Profit = 5x - 260
[/tex]

Answer:

An expression that represents the profit is:

[tex] Profit = 5x - 260 [/tex]
