QuestionGraph the cost of pumpkins ($0, 4, 8, 12, 16$ for $0, 1, 2, 3, 4$ pumpkins) and explain if it's proportional.

Studdy Solution
Calculate the slope.
$$lope = \frac{ -4}{2 -1} =4$$The slope is4, which means for every additional pumpkin bought, the cost increases by $4. This is consistent with the data in the table, confirming that the cost is proportional to the number of pumpkins.
