To find how many more bags of flour the baker used in the second week compared to the first week, you need to subtract the number of bags used in the first week from the number used in the second week:
Second week: 7310 bags
First week: 5710 bags
Calculation:
7310 - 5710 = 1600 bags
The baker used 1600 bags more in the second week than in the first week.
Based on the options available, it seems that 1610 bags is closest and might be a typo or error in the options. But if we are taking the exact difference, it is 1600 bags.
Therefore, based on the correct calculation, the answer is:
1600 bags (not explicitly given in the options). However, if you're required to select from the options, then 1610 bags would be the closest response.
