Notation
Let X be the average contribution size before John makes his contribution.
Let Y be the total contribution size before John makes his contribution.
Let Z be John's contribution.
We know that for this case $ 75 represent the original average amount before the contribution with 50% increase so we can set up the following equation in order to find the original average amount
And solvong for X we got:
Now we can find the total contribution before the donation with the following proportion:
And then with the formula of average taking in count the 6 values we can find the size of donation Z like this:
So then the correct answer is B. $200.
The list of scores from the given box-and-whisker plot are:
Lowest score: 20
Lower quartile (Q1): 30
Median: 60
Upper quartile (Q3): 80
Highest score: 100
The range = 80
<h3>How to Determine the Scores or Data Point from a Box-and-whisker Plot?</h3>There are specifically 5 values that are referred to as the five-number summary which are displayed by a typical box-and-whisker plot. As shown in the image attached below, these values include the following:
- The minimum value which is the least value
- The lower quartile value (Q1)
- The median value
- The upper quartile value (Q3),
- The maximum value which is the largest data score.
Thus, from the box-and-whisker plot that is given in this question, the five-number summary are:
Minimum value (lowest score): 20
Lower quartile value (Q1): 30
Median: 60
Upper quartile value (Q3): 80
Maximum value (highest score): 100
The range = max - min = 100 - 20
The range = 80
