Answer:
Assuming you want the amount of pens that Mai has left, the answer is 0.
Step-by-step explanation:
Mai has 8 packs of pens. She gives 5 away to Ervin and 3 away to Sara. In total, she gives away all 8 packs (because 5+3=8).
She started with 8, and gave away 8. This resulted in her having 0 packs left (because 8-8=0).
I hope this helps!
