Question 599103: How can i work out this problem I'm having trouble figuring it out?
The revenue of a charter bus company depends on the number of unsold seats. If the revenue in dollars, R(x), is given by
R(x)=x^2+50x+5000.
Where x is the number of unsold seats, find the number of unsold seats that produce maximum revenue. What is the maximum revenue?

You can put this solution on YOUR website!
check the function again i think it should be -x^2 +50x+5000
ok so do the derivative and set it equal to 0
-2x+50=0
x=25
now maximum revenue subsitute x =25
R(25)= -(25^2)+50(25)+5000
= -625+1250 +5000 = 5625.
