To determine the total amount that Sean could have spent on lunches for the past 6 weeks, we need to find the maximum and minimum amount he could have spent each week and then calculate the total range.
Given that Sean spent between $12 and $18 for a lunch each week, we can calculate the maximum and minimum amounts he could have spent in 6 weeks.
Minimum amount spent per week: $12 x 6 = $72
Maximum amount spent per week: $18 x 6 = $108
Therefore, the range of possible total amounts that Sean could have spent on lunches for the past 6 weeks is between $72 and $108.
Looking at the provided options:
A. Less than 80: This is within the range of possible amounts.
B. Between 60 and 120: This is the exact range of possible amounts.
C. Between 120 and 180: This is above the possible range.
D. Between 180 and 240: This is above the possible range.
E. More than 240: This is above the possible range.
Therefore, the correct answer is B. Between 60 and 120.
