Question

A home based sign company uses this function to model its montly profit, where x is the price of each sign it sells. What is the company’s profit if it sells each sign for $20?

Answer 1

Answer:

C. $4,460

Step-by-step explanation:

The monthly profit made, is a function of the price of each sign, x. Given the function that represents that models the monthly profit, $f(x) = -10x^2 + 498x - 1,500$, if the price, x, is $20, the monthly profit can be solved by simply plugging in the vakue if x into the given function equation as shown below:

$f(20) = -10(20)^2 + 498(20) - 1,500$

$f(20) = -4,000 + 9,960 - 1,500$

$f(20) = 4,460$

The monthly profit is $4,460.
