Jamila babysat nine times. She earned $15 $20 $10 $12 $20 $16 $80 and $18 for eight babysitting jobs. How much did she earn the ninth time if the mean of data set is $24?
Mean means add all the numbers and divide them by how many numbers are there. I used the Plug and Check Method and got $25 for the ninth time babysitting. Hope this helps!!!
