Answer:
5 weeks
Step-by-step explanation:
Let's find how much money she saves a week by multiplying the decimal form of 60% and $70.
To get the decimal form of a percent you have to move the decimal to the left twice, like this: 60 ---> .60
Now that we have the decimal form of the percent we can multiply it by the 70 to find how much she saves a week:
(70)(.6) = 42
Therefore, Kendra saves $42 each week.
To find how many weeks it will take Kendra to buy the game system you divide $210 by the $42. Like this:
(210)/(42) = 5
All in all, it will take Kendra 5 weeks to save enough money to buy a game system that costs $210.

Comment
You need two inputs. The first is the sum of the numbers and the second is the number of entries in the data.
Givens
Sum = 3 + 32 + 36 + 30 + 33 + 36
Number of entries = 6
Solution
Sum = 170
Mean = sum / number of enteries
Mean = 170 / 6
Mean = 28.33
