I don't see a chart, but, to find the mean you add all of the values up together and then divide by however many values you added.
For example, if she bakes 5 cakes one month, 7 cakes another month, and 2 cakes a final month, you'd add 5 + 7 + 2 to get 14. Then you'd divide 14 by 3, since you added 3 values together.
If you still need help, post the chart and I'll explain further.
Answer:
You would earn $81.25 per week.
Step by step process:
1 hour = $6.50 ( per hour means what you would get in an hour's time.)
12 1/2 = x
If more less divides. Let x be the subject. ( 12 1/2 is the same as 12.5 or 25/2)
x = 12.5 hours × $6.50 / 1 hour ( 1 hour will cancel out 12.5 hours 12.5 times.)
x= 12.5 × $6.50
x = $81.25
