If 3 pounds of grass cover 399 square feet, how many pounds are needed for 7182 square feet?
We can set up a proportion to solve this problem.
Let x be the number of pounds needed for 7182 square feet.
Using the given information, we can set up the proportion:
3 pounds / 399 square feet = x pounds / 7182 square feet
Cross-multiplying, we get:
399 * x pounds = 3 * 7182 square feet
Simplifying, we have:
399x = 21546
Dividing both sides by 399, we find:
x = 54
Therefore, 54 pounds are needed for 7182 square feet.
