Answer:
6 pounds of fertilizer
Step-by-step explanation:
So since we have the information for 4 pounds fertilizer per 120 sqft soil, To find out pound for pound per sqft, we'd take 120 and divide by 4.
120 divided by 4 is 30. So 1 pounds=30 sqft.
To find how much we need for 180 sqft, we'd multiply whatever number by 30!
Since we already know 4 x 30=120, we will want to go up from there!
5 x 30 = 150, not there yet, go up.
6 x 30 = 180, bingo!
So you need 6 pounds of fertilizer.
