Kamila babysat mine times. she earned $15,$20,$10,$12'$20,$16,$80,$18 for eight babysitting jobs. how much did she earn the ninth time if the mean of the data set is $24?
So, if 18 + 18 + 18 = 54 = 18 x 3 = 54 - 18 = 36 - 18 = 18, Every shift she made $18 If the data set is 24. She must be earning this method: 8 x 3 = 24 = 8 + 8 + 8 = 24$ There you go :D
