Two swim teams are selling spirit shirts to raise money.
One team is selling shirts for $8 each and has already raised $160.
The other team is selling shirts for $10 each and has already raised $150.
Which equation can be used to find x, the number of additional shirts each team needs to sell, so that the total amount raised is the same for both teams?
Responses
A 160x + 8 = 150x + 10
B 8x + 150 = 10x + 160
C 8x – 160 = 10x – 150
D 8x + 160 = 10x + 150

answered
First, we calculate the mean of the data set:
Mean = (88 + 72 + 77 + 95 + 65 + 80 + 70 + 106 + 65 + 68) / 10
Mean = 786 / 10
Mean = 78.6
Next, we calculate the absolute deviations from the mean for each data point:
|88 - 78.6| = 9.4
|72 - 78.6| = 6.6
|77 - 78.6| = 1.6
|95 - 78.6| = 16.4
|65 - 78.6| = 13.6
|80 - 78.6| = 1.4
|70 - 78.6| = 8.6
|106 - 78.6| = 27.4
|65 - 78.6| = 13.6
|68 - 78.6| = 10.6
Now, we find the mean of these absolute deviations:
Mean absolute deviation = (9.4 + 6.6 + 1.6 + 16.4 + 13.6 + 1.4 + 8.6 + 27.4 + 13.6 + 10.6) / 10
Mean absolute deviation = 109.2 / 10
Mean absolute deviation = 10.92
Therefore, the mean absolute deviation of the set of data is 10.92.
