Best ResponseYou've already chosen the best response.0Zero would be the amount that Marcy had previously. However, she borrowed $25 from her friend, which means that from her balance, she knows that she needs to give back that $25 (thus it is negative). However, she has only paid back $15, that means that she has only $10 remaining to give back and then she will get out from the negative range, so the arrow went to the right. From this information that I have given you, can you tell me what number line that would be?

Best ResponseYou've already chosen the best response.2your problem can be modeled by this expression: \[\Large  25 + 15\] since negative numbers are used to represent debts, whereas positive numbers are used to represent credits
