still cant get the answer....
Hi I cant solve these two optimization problems...
1. suppose that 20,000 fans will go to a ball game when the price of a ticket is $5, and that 500 fewer fans will go each $1 increase in price. What should the ticket price be in order to maximize revenue?
2. compute the max profit when the demand function is p(x)=x^2-3x+2 and the total cost function is c(x)=2x^3/3-1/2x^2-2x. Recall that r(x) = xp. Enter just a reduced fraction of form a/b.
Can anyone solve these?
- for the first one I set up in y-y1 = m(x-x1) form. with the points being (5,2000) and (6,19500). It came out to be y=-500x+22500. I then did R(x)=xp R(x)=x(-500x+22500) and distributed the x. Then i took the first derivitve and solved for 0. I got 22.5 but I think I solved for something else because that price is too high.
- As far as the second one I tried just plugging the two formulas in the formula p(x) = R(x)-c(x), taking the first derivitive and then solving for 0, but Im lost on it and really dont know what to do.
