How many more people need to ride the bus in week 6 to increase the mean number of riders per week by 10?
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
the total for the first 5 weeks is 85310.
the average for the 5 weeks is equal to 17062.
add 10 to that to get 17072.
multiply that by 6 to get 102432.
the number of passengers in the sixth week needs to be 102432 minus 85310 = 17122.
the average for the first 5 weeks is 85310 / 5 = 17062.
the average for the full 6 weeks is 102432 / 6 = 17072.
he needs 17122 passengers in the 6th week to get an average of 17072 each week.
