1. Assume that total revenue from the sale of x television sets is given by(adsbygoogle = window.adsbygoogle || []).push({});

R(x)=1000(1-(x/5))^2

a)find the marginal revenue when 400, 500, 600 sets are sold

i found that R'(x)=-4 +(x/125)

is it correct?

therefore R'(400)=$-0.8 R'(500)=$0 R'(600)=$0.8

??

b)find the average revenue form the sales of x sets

ave R(x)=R(x)/x

would it equal (1000/x)(1-(x/500))^2 ??

could it be simplify further?

c) Find the marginal average revenue.

ave R'(x)=R'(x)/x

=(-4/x)+(1/125)

am i correct on all of these??

2. The cost is dollars of manufacturing x items is given by

C=2000x+3500

demand equation is x=ā(15000-1.5p)

in terms of the demand x,

a) find an expression for the revenue R

does that mean R(x)=px

R(x)=pā(15000-1.5p)

or u solve for p instead?
