You sell tickets for a fundraiser. You give half of the tickets to your sister to sell. You sell 25 of your half of the tickets and have 17 left. How many tickets did you start with?

84 tickets

Step-by-step explanation:

So first off lets add the tickets we sold to the tickets we have left. Lets x equal the amount of tickets we started with before selling.

25+17=x

Add them up.

42=x

We started with 42 tickets. To find how many tickets we had before spiting the tickets. We need to multiply our tickets by 2 since we had half. Let y be this number

42*2=y

Multiply them up

84=y

We started with 84 tickets.
