Mai had 8 packs of pens. each pack had 10 pens. she gave 5 packs to ervin and 3 packs to sara

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).

=

=

⇒ option b is correct.
