In order to make some money for the annual charity drive, your school has decided to hold a carnival. They are looking for someone to be in charge of choosing the games that will make the most money. As a thank you, the person who is chosen will be given 4 tickets to a sold out concert for your all-time favorite music group. You would do ANYTHING to get your hands on those tickets.
One of the problems they need to know is what to charge for the games. Last year they charged $1.75 (small prizes), $2.85 (medium prizes), & $4.20 for the (large prizes). You know if you were in charge you would just round to the nearest dollar to eliminate all the change. The principal is also looking for someone who can estimate the number of people that will be attending the carnival. You believe there will be 867 students attending, but don't want to tell anyone. You worked all day on your calculations and don't want to forget the number, but you don't want anyone else to see it, so you are using your keyboard to make a code of the number with symbols.
So many people volunteer to fill the position that the principal decides to hold a contest in order to choose the best person for the job.
Since choosing the carnival games that will make the most money will be based on the game’s probability of the person playing winning or losing and solving some basic problems, the principal decides to set up a series of tasks that will test your knowledge of probability and solving problems. They will choose the person who can complete the tasks the fastest.
Find them and solve the puzzles to get the codes that will open the locks. You will need to work quickly but work through the answers carefully. Mistakes will cost you time. Everything you need is somewhere on this website.
Hope you have been paying attention in math class. You just HAVE to win those tickets!
Good luck!
