Solve multistep problem a household uses 1/4 of a 15 pound bag of rice every three weeks what is the change in the number of pounds in rice in a bag after eight weeks : -90 b:10 c -10 d: -2/3
To solve this problem, we need to find the change in the number of pounds of rice in the bag after eight weeks.
First, we need to determine how much rice is used in eight weeks. Since a household uses 1/4 of a 15-pound bag of rice every three weeks, they use 1/4 x 15 = <<1/4*15=3.75>>3.75 pounds of rice in three weeks.
Therefore, in eight weeks, they will use 3.75 x 8/3 = <<3.75*8/3=10>>10 pounds of rice.
Since the question asks for the change in the number of pounds of rice in the bag after eight weeks, we need to subtract the amount used from the original 15-pound bag.
The change is therefore 15 - 10 = <<15-10=5>>5 pounds.
Therefore, the answer is b) 10.
Are you sure it wouldn’t be negative because we’re getting smaller or decreasing
You are correct, I apologize for the mistake. Since the amount of rice in the bag is decreasing, the change should be negative.
The change in the number of pounds in the rice bag after eight weeks should be -10 pounds.
Therefore, the correct answer is d) -10.

To solve this problem, we need to calculate the change in the number of pounds of rice in a bag after eight weeks.
Step 1: Determine how many bags of rice are used in eight weeks.
Since a household uses 1/4 of a 15-pound bag every three weeks, we can calculate the number of bags used in eight weeks by dividing 8 by 3: 8 / 3 = 2.67
Step 2: Calculate the total weight of rice used in eight weeks.
Since each bag contains 15 pounds of rice, we can multiply the number of bags used (2.67) by the weight per bag (15 pounds): 2.67 * 15 = 40.05 pounds
Step 3: Determine the change in the number of pounds in a bag after eight weeks.
Since the initial weight of a bag is not given, we cannot determine the exact change in the number of pounds. Therefore, none of the provided options (-90, 10, -10, -2/3) is the correct answer.
Note: If we knew the initial weight of the bag, we could subtract the total weight used (40.05 pounds) from the initial weight to find the change.
To solve this multistep problem, we need to break it down into individual steps. Here's how you can approach it:
Step 1: Identify the given information:
- A household uses 1/4 of a 15-pound bag of rice every three weeks.
Step 2: Calculate how much rice is used in one week:
Since the information is given for every three weeks, we need to find the amount used per week.
1/4 of a bag is equivalent to 1/4 * 15 pounds = 3.75 pounds.
So, the household uses 3.75 pounds of rice every week.
Step 3: Determine how much rice is used in eight weeks:
To find the amount used in eight weeks, multiply the weekly amount by the number of weeks:
3.75 pounds/week * 8 weeks = 30 pounds.
Step 4: Calculate the change in the number of pounds of rice in a bag:
Assuming the initial bag had 15 pounds, we subtract the amount used from the initial amount:
15 pounds - 30 pounds = -15 pounds.
Step 5: Analyze the result:
The result is -15 pounds, which means there is a decrease in the number of pounds of rice in the bag after eight weeks.
Therefore, the correct answer is d) -15 pounds.
