Question

The revenue in dollars, R(x), of producing and selling x Awesome Hearing Aids is modeled by the function 

R(x)= x^2 +33x

What is the independent variable and its units? Incorrec

What is the dependent variable and its units? Incorrect

Answer 1

Revenue = R = yx = PQ = x^2+33x

y = yx/x = x+33

P= Q+33, is the linear demand function or average revenue function

R = x^2+33x is a parabolic quadratic total revenue function

x is normally the independent variable, measured on the x axis

Revenue = R(x) is the dependent variable, dependent on how much is purchased

x is measured by number of hearing aids sold, an integer unit

R is measured by a monetary unit, in the US, it's the US dollar
