The table shows the number of pounds of beef jerky purchased at a market and the total cost, in dollars, of the beef jerky. Determine whether the relationship between pounds of jerky purchased and total cost is proportional.

Question

beef jerky (pounds)|costs (dollars)
1 8
2 16
3 24
4 32
A

The relationship is proportional.
B

The relationship is not proportional.

Answer 1

B. The relationship is not proportional.

This can be determined by checking if the ratio of pounds of beef jerky to total cost is always the same.

For example, for 1 pound of beef jerky, the cost is $8. However, for 2 pounds of beef jerky, the cost is $16, which is not double the cost of 1 pound.

Therefore, the relationship between pounds of jerky purchased and total cost is not proportional.
