Answer:
Ill answer this and hope you meant subtraction if not, this is wrong.
20 - 20 = 0
Step-by-step explanation:
Well, you can't write an addition problem for subtraction which is the only thing happening in that situation, because Nikki is only losing money.
I think it may be negative twenty plus twenty equals 0? So -20+20=0? That is the only way I could think of to make it an addition problem. Sorry I don't know lol, hope this helps
