Math Challenge #4

Math Challenge #4

1. During the last wind storm there was a sandwich that was blown to the top of a 27 foot oak tree. This sandwich attracted a very hungry caterpillar that was determined to reach the delicious sandwich. This caterpillar could travel 4ft. during the day before he needed to go to sleep at night. While he was sleeping he would slide back 2 feet. How many days will it take him to reach the delicious sandwich?
2. Dr. Vick wants to make sure the concession stands at all of the gyms are making a profit. Popcorn seems to be the best seller at all of the concession stands. A 2 pound bag of popcorn costs $5.00 at Wal-Mart. You can make 20 bags of popcorn from the 2 pound bag of popcorn. The concession stand charges 50 cent per bag. How much of a profit are the gyms making off of the 2 pound bag of popcorn? Also, Dr. Vick wants to know how many bags of popcorn to buy if we want to make a 25 dollar profit?

3. Target has the new Wii-U for sale for $250. You and your brother have been saving for a long time. You have $68 and your brother has $62. If your brother receives $5 a week for allowance and you receive $5 a week for allowance, how many more weeks will it take you and your brother to get the new Wii-U?
