To find the mean you add all the numbers and divide it by the amount of numbers there is so add
6+9+15+22+30+36=118
there is 6 number so divide 118 by 6
118/6=19.6666666667 rounded to the nearest tenth it would be 20
So your mean would be 20

asambeis [7]

Calder would have to work 10 hours to equal the same amount Mika has from 9 hours of work

Here's how:
Since Mika works 9 hours and she gets 25 per 3 hours, to get her amount for 9 hours, you times 25 by 3 which is 75

Now you need to set up a equation
To make it easier. you can divide 15 by 2, which is 7.5, to get a unit rate
After that you can set up your equation
7.5x=75
x=10
Hope this helps:)
