Answer:
Table B
Step-by-step explanation:
we know that
A relationship between two variables, a, and b, represent a proportional variation if it can be expressed in the form [tex]b/a=k[/tex] or [tex]b=ka[/tex]
In this problem the table B shows a proportional relationship because
For a=20, b=25 -----> b/a=25/20=1.25
For a=24, b=30 -----> b/a=30/24=1.25
For a=32, b=40 -----> b/a=40/32=1.25
The constant of proportionality k is 1.25
