Answer:
None of the above.
Step-by-step explanation:
Given,
The area of ground covered by each bag = 12x square feet,
Let A be the total area of the land,
So, the total number of bags required = [tex]\frac{\text{total area}}{\text{area covered by each bag}}[/tex]
[tex]=\frac{A}{12x}[/tex]
Also, the cost of each bag = 22 dollars,
So, the total cost to cover the ground ( say C ) = number of bags required × cost of each bag
[tex]C=\frac{A}{12x}\times 22[/tex]
For minimizing C we need the value of A,
Hence, none of the given options are correct.
