Algebraic Equation for ticket sales as fcn of ticket price

[Luvbks1]

Please help...I have a test on this on Monday and I dont even understand it.

Concert Survey

Ticket Price ------------Estimated Ticket Sales
3 ------------------------- 1,500
4 ------------------------- 1,200
5 ------------------------- 900
6 ------------------------- 600
7 ------------------------- 300

Write algebraic equations that give the following:
* Ticket sales (S) as a function of ticket price (p)
* Income (I) from ticket sales as a function pf ticket price (p)
* Profit (P) as a function of ticket price (p)

Re: Algebraic Equation ?? Help

S = 300 * (8 - p)

I = p * 300 * (8 - p)

P depends on expenses...if no expenses, then same as I
