The average cost of producing a security system based on the total number of systems produced, x, is represented by the following function. f(x) = 400 + 20,000/x

The mathematical range is all real numbers excluding 0, but the reasonable range is limited to y >
what is the answer?

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":
