Answer 1

To find out how much Fred donated, we can analyze the increase in money collected for each increase in tickets sold.

- When Fred sold 5 tickets, he collected $275.
- When Fred sold 10 tickets, he collected $350.
- The increase from selling 5 more tickets resulted in an increase of $75 ($350 - $275).
- If all the tickets were sold at the same price, each ticket's value would be $75 / 5 = $15.

Since Fred recorded the number of tickets he sold and the total amount of money in the envelope, we can find out how much he donated by subtracting the total money collected from the sales from the money collected after selling 5 tickets:

$275 - $200 = $75.

Therefore, Fred donated $75.

So the correct answer is: $75.
