Answer:
B. The mean would increase.
Step-by-step explanation:
The Median is the middle value when the values are placed in order from smallest to largest. If there are two middle values, the median is halfway between them.
<u>Median for first three weeks</u>
$100, $125, $125
Therefore, the median is $125
<u>Median for 4 weeks</u>
$100, $125, $125, $125
Therefore, the median is ($125 + $125) ÷ 2 = $125
Therefore, the median has stayed the same
The Mean is the total of the numbers divided by how many numbers there are.
<u>Mean for first three weeks</u>
($100 + $125 + $125) ÷ 3 = $116.67
<u />
<u>Mean for 4 </u>
<u>weeks</u>
($100 + $125 + $125 + $125) ÷ 4 = $118.75
Therefore, the mean has increased.
