*spent (not spend)
To find out how much Jill spent in the past 8 weeks, we need to multiply the average amount she spends per week by the number of weeks.
Given that the mean amount Jill spends per week is $27.20, we can calculate the total amount she spent by multiplying this average by the number of weeks, which in this case is 8.
Calculation: $27.20 x 8 = $<<27.20*8=217.60>>217.60
Therefore, Jill spent a total of $217.60 in the past 8 weeks.
