Answer:
<u>## Profit/Loss = </u><u></u>
<u>## 29 tickets</u>
Step-by-step explanation:
Profit/Loss is Revenue - Cost
For the fundraisers:
Revenue comes from tickets sold at $14 each
x tickets sold, means the revenue is:
14x
Now, cost is what they are going to give out, that is $400 TV Set, so the cost is:
400
Hence, Profit/Loss would be:
<u>Profit/Loss = </u><u></u>
<u></u>
Raffle sales equaling the cost of prize is basically when we break-even, or when profit/loss is equal to 0. So we solve the equation:
Profit/Loss = 14x - 400
0 = 14x - 400
14x = 400
x = 28.57
We can't sell fractional tickets, so we have to sell 29 tickets in order to break even
