Laurie needs at least 40 pounds of topsoil for a new flower bed. Each bag of topsoil is 200 ounces. Laurie determines that if she buys 3 bags of topsoil she will have enough for the flower bed. Is Laurie correct? Why or why not?
A.
Laurie is not correct because the weight of 1 bag of topsoil is equivalent to only 10 pounds.
B.
Laurie is correct because 200 ounces is more than 40 pounds.
C.
Laurie is correct because the weight of 3 bags of topsoil is exactly 40 pounds.
D.
Laurie is not correct because the weight of 3 bags of topsoil is less than 40 pounds.
A. Laurie is not correct because the weight of 1 bag of topsoil is equivalent to only 10 pounds. 200 ounces is equal to 12.5 pounds, so 3 bags of topsoil would only provide 37.5 pounds of topsoil, which is not enough for her flower bed.

You're welcome!
To answer this question, we need to convert the weight of the bags of topsoil from ounces to pounds.
First, we need to know the conversion factor: 1 pound is equal to 16 ounces.
Next, we can calculate the weight of 1 bag of topsoil in pounds:
200 ounces / 16 ounces = 12.5 pounds.
Now, we can determine the total weight of 3 bags of topsoil:
3 bags * 12.5 pounds/bag = 37.5 pounds.
Since the weight of 3 bags of topsoil is 37.5 pounds, Laurie is not correct. The weight is less than 40 pounds, so she will not have enough topsoil for her flower bed.
Therefore, the correct answer is D. Laurie is not correct because the weight of 3 bags of topsoil is less than 40 pounds.
