Question

The marginal revenue for x items in dollars is given by r'(x)=-2.5x+7

determine and the revenue function and demand function

Answer 1

hi again
i looked in Stewart book and it gives "revenue function" is \(R(x)\) which in this case is \(R(x)=-1.25x^2+7x\)

Answer 2

then for the demand function \(P(x)\) it says that
\[R(x)=xP(x)\] so in this case the demand function would be
\[P(x)=-1.25x+7\]

Answer 3

leave the question open, maybe someone else will chime in, but that is what my calc text says

Answer 4

yes its correct thanks so much!
