Question

a campus republican fundraiser offers raffle tickets for 9$ each the prize for the raffle is a 450 tv which must be purchased with the proceeds from ticket sales. find a function that gives the profit/loss for the raffle as it varies with the number of tickets sold how many tickets must be sold for the ticket sales to equal the cost of the prize

Answer 1

If each ticket is $9 the amount of money made from tickets is the number of tickets sold (lets call this t) multiplied by 9. So the amount of money from tickets is 9t.

Profit = 9t

But remember that you have to subtract the cost of the TV because that isn't part of your profit.

Profit = 9t - 450

If the ticket sales equaled the cost of the prize then 9t = 450, solve for t!
