Students 24 16
Canned Food 30 22
Dry Food 42 24

Answer 1

Let x be additional food item the homeroom B should collect  to have greater item per student than homeroom A.

(22 +24 + x) / 16 > (30 + 42 + 21) /24

(22 +24 + x) > 3.875 (16)

X > 16

So they should collect more than 16 food item to have a greater item per student
