Each problem will be displayed for 1 -2 minutes. The PARTNERS must then work together to determine the solution. You may only bet UP TO HALF of your money at any time You may choose to bet $0 ONE TIME ONLY Your best must be in increments of $50, so round down if you are short You are responsible for keeping track of your $$ (be honest…) If it’s correct, partners add the amount they bet to their total. If it’s incorrect, it’s deducted from their total. The group with the most $$$ at the end wins. WE WILL ALSO LOOK FOR THE RICHEST PAIR OF PARTNERS IN THE OVERALL CLASS. HAPPY BETTING!!
