Question

A company sells bikes that are light and fast. The revenue earned over a period of x years can be represented by the function, S(x) = 100x3 + 6x2 + 97x + 215. The cost of manufacturing the bikes can be represented by the function, C(x) = 88x + 215. Which function, P(x), describes the profit earned from the sales of the bikes over a period of x years?

Answer 1

I agree! It's answer A.) P(x) = 100x3 + 6x2 + 9x

Explanation:

The function for the profit earned from the sales of the bikes over a period of x years can be calculated by subtracting the cost of manufacturing in x years from the revenue earned.

To find P(x), subtract C(x) from S(x).

Answer 2

The first choice

Explanation:

The selling Price is S(x) = 100x^3 + 6x^2 + 97x + 215

The cost = C(x) = 88x - 215

The Profit = S(x) - C(x) = 100x^3 + 6x^2 + 9x

The answer is The First Choice
