To find the total weight of the four bags of potatoes, you simply need to add their weights together. Here are the weights provided:
- 5.72 pounds
- 3.112 pounds
- 3.4 pounds
- 3.11 pounds
Now, let's add them up:
\[ 5.72 + 3.112 + 3.4 + 3.11 \]
Calculating step by step:
- \(5.72 + 3.112 = 8.832\)
- \(8.832 + 3.4 = 12.232\)
- \(12.232 + 3.11 = 15.342\)
Thus, the total weight of the bags is 15.342 pounds.
