So the answer is stay the same

Hope I helped brainlest???

Answer:

C) stay the same

Step-by-step explanation:

Find the two means

$10, $20, $ 25, $30, $40.

Mean 1 = (10 + 20 + 25 + 30 + 40) /5 = 125/5 = $25

She gets another mail with $25

$10, $20, $ 25, $25 $30, $40.

Mean 2 = (10 + 20 + 25 + 25 + 30 + 40) /6

= 10/6

Mean 2 = $25

Both means are the same.

Therefore, answer C) stay the same

Hope this will helpful.

Thank you.
