Answer:
A. 35
Step-by-step explanation:
The median of a data set is the middle value when the data values are placed in order of size.
<u>Given data set</u>:
- {3, 35, 23, 37, 45, 5, 49, 27, 48}
Place the data in <u>order of size</u>:
- {3, 5, 23, 27, 35, 37, 45, 48, 49}
To find the median, divide the total number of data values (n) by 2.
- If n/2 is a whole number, the median is halfway between the values in this position and the position above.
- If n/2 is not a whole number, round it up to find the position of the median.
As there are 9 data values, the median value is:
Therefore, the median of the given data set is 35.
Given:
Michelle plans on raising $80.
Selling price of each shirt = $10
So far she has raised $20.
To find:
The number of more shirts she needs to sell.
Solution:
Let x be the number of more shirts she needs to sell.
Selling price of one shirt = $10
Selling price of x shirt = $10x
Total raising amount = $(10x + 20)
Michelle plans on raising $80. So,
Subtract both sides by 20.
Divide both sides by 10.
So, the required equation is
Therefore, the correct option is A.
