Answer:
25 lb bag of fertilizer can cover 10 square feet of lawn.
Step-by-step explanation:
Given:
5 pounds of fertilizer cover = 2 [tex]ft^2[/tex] of the lawn
We need to find the 25 lb bag cover.
Solution:
Now we know that;
5 pounds of fertilizer = 2 [tex]ft^2[/tex] of yard.
1 lb of fertilizer = Number of [tex]ft^2[/tex] lawn covered by 1 lb fertilizer.
Using Unitary method we get;
Number of [tex]ft^2[/tex] lawn covered by 1 lb fertilizer = [tex]\frac{2}{5}\ ft^2[/tex]
Now we can say that;
1 lb of fertilizer = [tex]\frac{2}{5}\ ft^2[/tex] of the yard
25 lb of fertilizer = Number of [tex]ft^2[/tex] lawn covered by 25 lb fertilizer.
Again by using Unitary method we get;
Number of [tex]ft^2[/tex] lawn covered by 25 lb fertilizer. = [tex]\frac{2}{5}\times 25 = 10 \ ft^2[/tex]
Hence 25 lb bag of fertilizer can cover 10 square feet of lawn.
