Jacqueline was trying to leave a plate of cookies for Santa, but people kept nibbling on the treats. First Ernie snuck in and ate 2 cookies. Then Michelle quietly pilfered one-fifth of the remaining cookies. Nicole figured she was getting a stocking full of coal anyway, so she swiped one-fifth of the cookies left on the plate. Jacob was starving after a night of Christmas caroling, so he gobbled up four cookies. Mario then snacked on one-half of the cookies that were left. Then Phillip took two cookies off of the plate and stored them away for winter. This left only four cookies for Santa, and the jolly old elf left many of Jacqueline's presents in his sleigh. How many cookies did Jacqueline originally leave for Kris Kringle Kathryn's friend wasn't quite awake when she took Kathryn's jet ski out in the bay. She forgot to untie it from its anchor, and when she got to the end of the rope, the ski stopped - but Kathryn's friend kept going. The jet ski is now attached to the end of a 30-foot anchor chain moving in a circle at a constant speed of 20 miles per hour. If the ski goes for one hour before it runs out of gas, how many times will it go around the circle? How far will the ski have traveled? Return to Problems of the Week Page	Math...
