If 15 pounds of fertilizer will cover 1500 square feet of lawn, how much fertilizer is needed to cover 2500 square feet?

Answer :

Determine how much fertilizer is needed to cover 2500 square feet, we can use a proportion based on the given information.

Given that 15 pounds of fertilizer covers 1500 square feet of lawn, we can set up the proportion:

15 pounds / 1500 square feet = x pounds / 2500 square feet

To solve for x, we can cross-multiply and solve for x:

15 * 2500 = 1500 * x

37500 = 1500x

Dividing both sides by 1500, we find:

x = 37500 / 1500 = 25

Therefore, you would need 25 pounds of fertilizer to cover 2500 square feet of lawn.
