Question 982884: I have tried to do this problem several times now and not really sure about what I am doing

Your drama club wants to sell tickets to your upcoming play. Based on previous experience,you have determined that the profit you can make on selling t tickets is given by this function. P(t)=14t-0.1t^2
a. How many tickets do you need to sell to get the maximum profit?
My answer: 280
b. What is the maximum profit?
My answer:Im not sure am not sure.
c. What price per ticket should you charge to make this profit? Explain how you figured this out.
My answer: I am not sure

Your drama club wants to sell tickets to your upcoming play.
Based on previous experience,you have determined that the profit you can make on selling t tickets is given by this function. P(t)=14t-0.1t^2
:
a. How many tickets do you need to sell to get the maximum profit?
We can write this as quadratic equation: y = -.1t^2 + 14t; a=.-1; b=14
Maximum will occur on at the axis of symmetry t = -b/(2a)
t = %28-14%29%2F%282%2A.1%29
t = %28-14%29%2F-.2
t = 70 tickets for maximum profit
:
b. What is the maximum profit?
Replace t with 70 in the original equation
P(t) = 14(70) - .1(70^2)
P(t) = 980 - 490
P(t) = $490 is the max profit
:
c. What price per ticket should you charge to make this profit? Explain how you figured this out.
Divide the total amt by the number of tickets
490/70 = $7 per ticket
