you guys don't even awsers
Apparently no math tutor has seen this post yet. We are volunteers and are not here all the time. To get help, though, we ask that you show your work. You have not done that. What do YOU think the answer is? We won't do your work for you.
To solve this problem, you need to calculate the total weight of the apples and grapes separately, and then find their sum.
The problem states that Bonita brought 3 bags of apples and each bag weighed 4 pounds. So, you will need to multiply the number of bags (3) by the weight of each bag (4).
Next, the problem states that Bonita also brought 2 pounds of grapes. Therefore, you will need to add the weight of the grapes (2) to the weight of the apples that was calculated previously.
To summarize:
- Multiply the number of bags of apples by the weight of each bag: 3 bags × 4 pounds/bag = 12 pounds of apples.
- Add the weight of the grapes: 12 pounds of apples + 2 pounds of grapes = 14 pounds.
So, the correct calculations to solve this problem are option D: multiply 2 × 4 (which is 8), and then add 3 to the product (8 + 3 = 11). However, none of the given answer choices reflect this correct calculation.
