Elementary school class played a partner game called just the facts to them learn multiplication facts. each player took turns rolling a pair of 10-sided dice (with digits 0-9) and announced the product of the two numbers. the other player checked the product with a calculator. if the answer given was correct, the player scored 5 points. the teacher wanted to discourage his students from guessing, so the penalty for an incorrect answer was losing 7 points! a) zach and jorge played 24 rounds. at the end, zach's final score was 0. out of his 24 turns, how many multiplication facts did zach get correct? show your work used to solve this problem and explain your reasoning. (parts b and c are on the back) b) the next day the boys played again. zach got the same number of facts correct, but this time his final score was 28. how many turns did he take? show your work used to solve this problem and explain your reasoning. c) on the third day, zach and jorge played the game again. what is the fewest number of turns that jorge could take to have a final score of 59? show your work used to solve this problem and explain your reasoning.
