Carla uses 2 pounds of Feed-All fertilizer for a 100-footrow of vegetables at her farm. at this rate, how many pounds of fertilizer would she use for a 450-foot row of vegetables? explain

9 pounds

Step-by-step explanation:

Because she is using 2 pounds per 100 footrow and 100 times 4 is 8 so that leave her with just 50 footrow she has to do and since thats half of 100 she only needs half the fertilizer which is 1. 8 + 1 = 9
