Final answer:
The increase in the amount spent on lunch in the second week compared to the first is $2. Hence the correct answer is option B
Step-by-step explanation:
To find the increase in the amount spent on lunch in the second week compared to the first, we need to calculate the difference in the total amount spent in the two weeks.
In the first week, Devon spent $12 + $9 + $10 + $5 + $9 + $8 = $53 on lunch.
In the second week, he spent two dollars more in total and for the five lunches than the first week. Let's assume the total spent in the second week is $53 + $2 = $55.
The increase in the main for the second week compared to the first is $55 - $53 = $2.
Therefore, the correct answer is B. $2.
