Answer:
The selling price be $79.56 .
Step-by-step explanation:
Let us assume that the cost price be x.
As given
If the markup is $8.95 and the overhead is $4.31 .
Selling price = Cost price + Markup price + Overhead price
= x + 8.95 + 4.31
= x + 13.26
Profit = Selling price - Cost price
= x + 13.26 - x
= $ 13.26
Formula
Putting the values in the above formula
x = $ 66.3
Thus cost price be $66.3 .
Thus
Selling price = $66.3 + $13.26
= $ 79.56
Therefore the selling price be $79.56 .

Step-by-step explanation:
Given that an automatic machine is set to fill bags of dog food with exactly 25 pounds on average with a standard deviation of 0.5 pounds.
Sample size = n =100
x bar = 24.85 pounds
Sample std error =
Hypotheses:
(Two tailed test at 5% level)
Mean difference =0.15
Test statistic = mean diff/se = 3
Since population std dev is known z test can be used
p value =0.0000
Since p <0.05 we find that the bag does not contain exactly 25 pounds.
