Answer:
6 pounds of fertilizer
Step-by-step explanation:
we know that
The directions say to use 4 pounds of fertilizer for 120 square feet of soil
so
using proportion
Find out how many pounds of fertilizer to use for 180 square feet of soil
Let
x ----> the number of pounds of fertilizer to use
[tex]\frac{4}{120}\frac{lb}{ft^2}=\frac{x}{180}\frac{lb}{ft^2}\\\\x=180(4)/120\\\\x=6\ lb[/tex]
Answer:
6 pounds of fertilizer is required to cover an area of 180 square feet.
Step-by-step explanation:
We are given the following in the question:
We have to use 4 pounds of fertilizer for 120 square feet of soil.
We find the equivalent ratio of area of soil and amount of fertilizer used.
Ratio =
[tex]\displaystyle\frac{\text{Area of soil}}{\text{Amount of fertilizer used}} = \frac{120}{4} = \frac{30}{1} =30:1[/tex]
This means that 30 square feet of soil requires 1 pound of fertilizer.
Area of the garden = 180 square feet
Let x be the amount of fertilizer required.
Thus, we can write:
[tex]\displaystyle\frac{30}{1} = \frac{180}{x}\\\\x = \frac{180}{30} = 6[/tex]
Thus, 6 pounds of fertilizer is required to cover an area of 180 square feet.
