1. Assume that total revenue from the sale of x television sets is given by
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=√(150001.5p) in terms of the demand x, a) find an expression for the revenue R does that mean R(x)=px R(x)=p√(150001.5p) or u solve for p instead?

o..my mistake...the question is actually
R(x)=1000(1(x/500))^2 then is my answer right now?
