A community group is selling prize tickets to raise money for a city park. The group spent $300 on prizes and sells tickets for $30 each. How many tickets does the group need to sell to raise $900?

Okay, so if you'll want to start out by adding 300 to the 900 they want to raise. This is because they want to raise 900 dollars, and they've already spent 300 on prizes and stuff. So, they want to raise 1,200 in order to make back the money they've spent in addition to the 900 they want to make for the city park.

If they sell each ticket for $30, that means they have to sell 40 tickets to make the minimum amount of $1200.

The group needs to sell 30 tickets. 900 divided by 30 is 30, so thats how you get your answer.
