We can adjust the data by adding 4 to everything before we calculate the statistics. Or we can calculate the statistics on the given data and just add 4 to everything at the end. We'll get the same answer either way.
Let's sort the seven data points: 5 5 5 7 7 9 10
Those add up to 48 so the mean is 48/7 = 6.9
The one in the middle is 7 so the median = 7
The mode is the most common one, mode = 5
The range is the difference between max and min, so range = 10 - 5 = 5
In the second week we add four to everything. Since that adds four to the min and max, the range doesn't change.
Answer: mean=10.9, median=11, mode=9, range=5

Answer: 116.2°</h3>
Work Shown:
The first equation is one of the three variations for the Law of Cosines.
Make sure your calculator is in degree mode.
Find the base price per pound, $15/11, or $1.36 = 1lb, then multiply it by 16, 16 x 1.36 = $21.82. Now just subtract $20 from $21.82 = $1.82. So, You would save, on average, $1.82 by buying the sale.
