Yes, it is true the cost of a pumpkin is proportional to the number bought.

What is the Proportional Relationship?

We are given the table showing cost of each number of pumpkins. Now, let us analyze the table values;

1) When number of pumpkins is 1, then cost is $4. Thus;

Cost per pumpkin = 4/1 = $4 per pumpkin

2) When number of pumpkins is 2, then cost is $8. Thus;

Cost per pumpkin = 8/2 = $4 per pumpkin

3) When number of pumpkins is 3, then cost is $12. Thus;

Cost per pumpkin = 12/3 = $4 per pumpkin

4) When number of pumpkins is 4, then cost is $16. Thus;

Cost per pumpkin = 16/4 = $4 per pumpkin

In all these rates, we see that the cost rate for pumpkins remains the same. Thus, we can conclude that it is true the cost of a pumpkin is proportional to the number bought.
