Can someone help me?

B. Yes, 3.5

Step-by-step explanation:

Proportional Variables

Two variables x,y are proportional if one of them can be calculated as the other variable time a fixed constant:

y = k.x

Or, equivalently:

k = y/x

k is called the constant of proportionality.

The table gives three points: (13,45.5) (14,49) (15,52.5)

To find out if the values correspond to a proportional relationship, we find the value of k for each pair:

k = 45.5 / 13 = 3.5

k = 49 / 14 = 3.5

k = 52.5 / 15 = 3.5

Since the value of k is the same for all the points, we conclude the table shows a direct proportional relationship and the constant of proportionality is 3.5
