Do the information on a bag of fertilizer 5 pounds of fertilizer are needed for every two square feet of lawn how many square feet will a 25 lb bag cover

Answer 1

Answer:

25 lb bag of fertilizer can cover 10 square feet of lawn.

Step-by-step explanation:

Given:

5 pounds of fertilizer cover = 2 $ft^2$ of the lawn

We need to find the 25 lb bag cover.

Solution:

Now we know that;

5 pounds of fertilizer = 2  $ft^2$ of yard.

1 lb of fertilizer = Number of $ft^2$ lawn covered by 1 lb fertilizer.

Using Unitary method we get;

Number of $ft^2$ lawn covered by 1 lb fertilizer = $\frac{2}{5}\ ft^2$

Now we can say that;

1 lb of fertilizer =  $\frac{2}{5}\ ft^2$ of the yard

25 lb of fertilizer = Number of $ft^2$ lawn covered by 25 lb fertilizer.

Again by using Unitary method we get;

Number of $ft^2$ lawn covered by 25 lb fertilizer. = $\frac{2}{5}\times 25 = 10 \ ft^2$

Hence 25 lb bag of fertilizer can cover 10 square feet of lawn.
