PLEASE ANSWER BOTH PARTS! THERE WILL BE A REWARD AND EXTRA POINTS! Maya has m baseball cards. She puts half of her cards in a pile to give to her brother and sister. She gives 12 of these cards to her brother and then gives the rest of these cards to her brother and then gives the rest of the pile to her sister Trisha. The expression m/2 - 12 can be used to find the number of cards Trisha gets from Maya.
PART A:
Maya thinks she started with 20 cards. If Maya is right, then according to the expression, how many cards would Trisha get?
PART B:
Do you think Maya started with a total of 20 cards? Use the drop down menus to explain your reasoning. Maya (could or could not) start with 20 cards. In order for Trisha to get at least 1 card, the minimum number of cards Maya can start with is (18, 22, 24, 26, or 30). If Maya starts with 74 cards, then Trisha gets (25, 31, 37, 49, or 62)
