Part C Find each player’s total score when they do not round after each turn and when they do round after each turn. Does rounding the scores to the nearest ten after each turn change the outcome of the game? Explain.
Part D Sara and De’Quan decide to play the game again. The results are shown in this table. This time they decide to round their scores to the nearest ten at the very end of the game. Find each player’s total score, and then round the scores to the nearest ten. Who wins the game?
