## anonymous 4 years ago The total revenue obtained from selling 'x' hundred items in a particular day is given by R, which is the variable 'x'. Given that dR/dx=20-4x; [a] Determine the total revenue function R. [b] Find the number of items sold that would maximize the total revenue and evaluate this total revenue.

ahh so you have taken calculus? for last problem wasn't sure...of course to maximize set derivative equal to 0

2. anonymous

to find R(x), integrate 20-4x $R(x) = \int\limits_{}^{}(20-4x) dx$

3. anonymous

which would give us 20x-2x^2

4. anonymous

yep
